How to use redux state data in a link?

I am new to redux and reactjs. I am trying to use a state data called type in the link I am fetching using axios in line no 17. I am setting the value of type from another .jsx file using dispatch().

Here in Home.jsx file I am calling dispatch in line no 24 for updating the state value type with onClick event.

Home.jsx

import React from 'react';
import '../styles/home.scss';
import { Link } from 'react-router-dom';
import { setType } from '../redux/imageSlice';
import { useDispatch } from 'react-redux';

const Home = () => {
  const dispatch = useDispatch();

  return (
    <div className="container">
      <div className="row">
        <div className="col-sm-6 col-md-4 d-flex justify-content-center my-3">
          <div className="ci">
            <img
              className="img-fluid"
              src="https://res.cloudinary.com/djz3p8sux/image/upload/v1662295247/web-projects-images/natures_hodrkk.jpg"
              alt="Nature"
            />
            <Link to="/nature">
              <div className="middle">
                <div
                  className="text"
                  onClick={() => dispatch(setType('nature'))}>
                  Nature
                </div>
              </div>
            </Link>
          </div>
        </div>
      </div>
    </div>
  );
};

export default Home;

imageSlice.js

import { createAsyncThunk, createSlice } from '@reduxjs/toolkit';
import axios from 'axios';

const initialState = {
  type: '',
  images: [],
  error: null,
  isLoading: false,
};

const config = {
  Authorization: '563492ad6f91700001000001350d302e175b4c208aac413953d6edcc',
};

export const fetchImages = createAsyncThunk('images/fetchImages', async () => {
  const res = await axios.get(
    `https://api.pexels.com/v1/search?query=${initialState.type}&per_page=15`,
    {
      headers: config,
    }
  );
  return res.data;
});

export const imageSlice = createSlice({
  name: 'images',
  initialState,
  reducers: {
    setType: (state, action) => {
      state.type = action.payload;
    },
  },
  extraReducers: builder => {
    builder.addCase(fetchImages.pending, state => {
      state.isLoading = true;
    });
    builder.addCase(fetchImages.fulfilled, (state, action) => {
      state.isLoading = false;
      state.images = action.payload;
      state.error = null;
    });
    builder.addCase(fetchImages.rejected, (state, action) => {
      state.isLoading = false;
      state.images = [];
      state.error = action.error.message;
    });
  },
});

export const { setType } = imageSlice.actions;

export default imageSlice.reducer;

store.js

import { configureStore } from '@reduxjs/toolkit';
import imageReducer from './imageSlice';

export const store = configureStore({
  reducer: {
    images: imageReducer,
  },
});

How to do that? I am trying to update the fetching link using state type value on line 17 in imageSlice.js file.

One option is to provide the type to fetchImages by parameters (see payload):

export const fetchImages = createAsyncThunk('images/fetchImages', async (payload) => {
  const res = await axios.get(
    `https://api.pexels.com/v1/search?query=${payload.type}&per_page=15`,
    {
      headers: config,
    }
  );
  return res.data;
});

Then you need to provide the type to the function, when calling fetchImages. Here in an example component:

import { fetchImages } from '../redux/imageSlice';
import { useDispatch, useSelector } from 'react-redux';

function YourCallingComponent(props) {
    const dispatch = useDispatch();
    const currentType = useSelector((state) => state.type);

    function fetchImagesOfType() {
        dispatch(fetchImages({
            type: currentType
        }));
    }
    
    return (
    ...
    )
}
