The user-level commands for evaluation are defined in geise-mode.el. If
you look at any of them (geiser-eval-last-sexp, geiser-eval-region,
etc.), you'll see they rely on geiser-debug--send-region, which is the
one popping up debugging info after evaluation. There's also
geiser-debug--send-region/wait, to make the evaluation synchronous.

I am not sure I understand what you want to do, but if the sexp is still
in the buffer, geiser-eval-last-sexp is probably good enough. If you're
massaging the code or generating some, you could put it in temp buffer
and then use there those functions, after activating geiser-mode there
(which can be tricky if you use more than one scheme), or create your
own version of geiser-debug--send-region which takes a string, the one
defined here:

https://gitlab.com/emacs-geiser/geiser/-/blob/master/elisp/geiser-debug.el#L265

Hope that helps.

Cheers,
jao
