Excel on MS TEAMS

[Dharris144]

Ok first I will apologize cause this is not just an Excel question.

I have Excel workbooks linked to each other on a file share. I wan to move them to TEAMS which essentially is SharePoint on the backend.
The question is how do I link sheets form one file in TEAM A to a file in TEAM B?

I can open the files in SP but still do not know how to update the links like a normal spreadsheet.

Thanks in advance for any help you can give.
