I'm guessing that's because your LSP server isn't configured or able to
do that.

I successfully use Eglot with Digestif[1].  I would try TexLab[2] that
Joost mentioned as well but it's not as easy for me to compile it given
the version of Rust on Debian.

Eglot also works OOTB, except for one minor detail: I have to remap
AUCTeX's binding of TeX-complete-symbol back to the default
completion-at-point, which Eglot hooks into.
