This is my code. Whenever I try to check the link, it ends up returning an error message. What can I do to fix this?

window.addEventListener('load', ()=>{
    let lon;
    let lat;
    if(navigator.geolocation){
        navigator.geolocation.getCurrentPosition(position => {
            lon = position.coords.longitude;
            lat = position.coords.latitude;

            const api = `https://api.openweathermap.org/data/2.5/weather?lat={lat}&lon={lon}&appid=432199bc4e2df182e56f173156ed4922
            `;

        });
        
    }else{
        h1.textContent = "NOT WORKING"
    }

});
