I can’t figure out how to stick it into my canvas in the place I need

Answer 1

No way, the KGL library does not provide for
this. You can try to make a fork and publish it for yourself (in git or npm), if you're lucky, but the author will accept the pull request quickly.
Or try a tricky trick - replace document.body before initializing Kgl, but this can break something

var origBody = document.body;
document.body = yourTargetParent;
const webgl = new Kgl...
document.body = origBody;
