can someone guide how to share files within a group??

Hi, I’m new to salesforce how can restrict users to view the files uploaded by their group.
ex: there are Group A and Group B. The files that belong to group A should be accessible to group A only and the same for Group B.I’m using share point as my 3 rd party for file storage.
Can someone guide me on this? It will very much helpful.
Thank you!
