How to define an internet brower for gmailr authentication?

Question

I use gmailr to retrieve emails from a gmail account. Due to my system configurations (nix home-manager on Debian), when gmailr needs an interactive connection to gmail, nothing happens, it just waits forever.

Waiting for authentication in browser...
Press Esc/Ctrl + C to abort

It was working fine, until I remove the old brower form /usr/bin/, and install it through nix to ~/.nix-profile/bin/. Is there a way to tell gmailr or gargle maybe, which browser to use for the authentication procedure?

I wasn't able to find something in docs or google.

Edit: I now found, that the problem relies on the way gmailr starts the browser from the system environment, I get this error:

Waiting for authentication in browser...
Press Esc/Ctrl + C to abort
/usr/bin/env: ‘.nix-profile/bin/brave’: No such file or directory

So I need to find a way to override the environment path....

I realize that there is an option in R for selecting the default browser!

So I just put options(browser = "x-www-browser") in my gmailr script or in my .Rprofile. Where "x-www-browser" is a system alias for my selected browser, but it can be any system path.
