Help needed Configuring Thunderbird

Can anyone point me to clear, simple instructions with examples on how to set up-configure thunderbird mail client on my PC running Debian 10+ -11+ ?
I think I might need a plugin written for it, so can anybody direct me to any site to find a capable developer ?

Could you please explain, what your issue is?

Agreed. Thunderbird sets itself up quite nicely. Evolution is nearly as capable as well.

I guess my question would be what’s missing in Thunderbird that you can’t set it up?
this page may be of help if thunderbird is not installed.
