And the help topic is at
:h :syn-fold

I don't know why you insist on folding by syntax, it doesn't make sense
for your language (imho). The opening marker contained in the linewise
comment need to extend that comment over several lines up to the closing
marker, it's not one-line anymore.

And fdm=syntax is also known to be slow.

And you cannot create/delete folds with `zf', `zd' etc. but maybe that
is intended?
