consult-completion-in-region, lsp-mode method signatures

[stevemolitor]

Using corfu + marginalia in lsp-mode I can see method signatures and documentation for completion candidates:

With consult-completion-in-region I only see the method names:

Is it possible to get at least the method signatures when using consult-completion-in-region in lsp-mode?

I don't use auto-completion. I only use on-demand completion.

EDIT: Alternately is there a way to use embark to show the signature or documentation on demand for a candidate within the minibuffer? That might be ideal actually.

Unfortunately I cannot give you much assistance regarding lsp-mode and consult-completion-in-region, since I don't use lsp-mode and consult-completion-in-region only sparingly. As mentioned in the README, consult-completion-in-region is not expected to work well with lsp-mode, since the lsp-completion-at-point-function expects the input to arrive in the original buffer (and not in the minibuffer). That being said, I cannot explain why annotations don't work in this case. In principle they should work. Maybe the lsp-mode maintainers have some insight?
