from this code for make visible long lat coordinate after moving the mouse over the map. And I rewrite to HTML page with newest OpenLayers version.
I would like to show this long lat coordinates after click to some place in map, not after move mouse on map as in the code. And make visible last coordinate until someone click to next place, nothing. I don't want the coordinates to disappear right away as in code.

Use singleclick or click event on your map:
map.on('singleclick', event => {
const coordinate = ol.proj.toLonLat(event.coordinate);
const innerText = `Lon: ${coordinate[0].toFixed(4)}, Lat: ${coordinate[1].toFixed(4)}`;
document.getElementById('myposition').innerText = innerText;
});
