MS Teams chat contacts

Hello everyone.

I am using MS Teams on two computers. I created a contact list divided with contact groups on one computer.

Is there a file or a folder (local or online) containing this list? I need to use this list of contacts on the other machine. I would like to avoid creating the list by adding people one by one.

It is not about importing contacts from other applications. Just copying the list of contacts from one Teams application to another (to the other computer).

I would be obliged for your help

Best regards

Tomasz
