Auto excluding selector resembling a toggle

I’ve being searching around and found some jQuery and Vanilla answers. I even found the exact answer to my problem, but it did not work within the rest of my code. So I have come with this adapted code which I took from this question Show / Hide Div on Click with JavaScript and it works fine but…as far as it is when I choose and option it appears, fine, but I would like that if I select the other option, then the previous turns hidden. What I mean, I need only one of the options displayed at once. This is my code:

function setCup(elementId) {
    const element = document.getElementById('pymntCup');

    if (element.style.display === "block") {
        element.style.display = "none";
    } else {
        element.style.display = "block";
    }
    }
    function setUsd(elementId) {
    const element = document.getElementById('pymntUsd');

    if (element.style.display === "block") {
        element.style.display = "none";
    } else {
        element.style.display = "block";
    }
    }

.flag-icon-wrapper {
    margin-right: 20px;
    padding-top: 5px;
    }
    .flex {
    display: flex;justify-content:space-evenly;
    }
    h3 {
    text-align:center;
    }
    .is-shown-initially {
    display: block;
    }
    .is-hidden-initially {
    display: none;
    }

<h3>Select a payment mode</h3>

Answer

You can set the other one to none

function setCup(elementId) {
const element = document.getElementById('pymntCup');

//Here you can set the other one to none 
document.getElementById('pymntUsd').style.display = "none";

if (element.style.display === "block") {
    element.style.display = "none";
} else {
    element.style.display = "block";
}

}

Likewise here too

function setUsd(elementId) {
const element = document.getElementById('pymntUsd');

//Here you can set the other one to none 
document.getElementById('pymntCup').style.display = "none";

if (element.style.display === "block") {
    element.style.display = "none";
} else {
    element.style.display = "block";
}

}
