connecting tor to vpn

I have a problem.
I downloaded a vpn extension to tor to access the internet in a certain country, as tor selects the country randomly as I understand it. But after running this extension I can’t connect to tor at all.
Is there any way to deploy vpn inside whonix so that it works?
I’m just getting started with the whonix interface and terminal, so this question is causing me some difficulty in solving it on my own so far.
If there is a similar thread on how to solve this problem? please share the link to it.
I hope my question has been asked accurately so as not to cause ambiguity.
Thanks in advance for your reply!
