All you need is to concatenate the Round variable.

const Round = 1;
return fetch('http://myurl/data.php?ID='+Round);

return fetch(`http://myurl/data.php?ID=${Round}`);

const round = 1;
return fetch(`http://myurl/data.php?ID=${round}`);

Note: regular variables should have lowercase names, by convention.

Just put const variable at the end

For Example :

const Round = 1;

return fetch('http://myurl/data.php?ID='+Round)
