Add-PnPTeamsTab - How to get the -EntityId while creating a tab using PnP?

[kunalIkea]

Hello Team,

I need to add an Excel/PPTx file as a Tab in a Channel in Teams. And for that we need to provide the -Entityid as mandatory parameter.

Do we have any cmdlet to get the -EntityId of the file? Or do we have any other workaround to achieve the required results?

If we add a Tab manually into Teams, then we may get the -EntityId. But this not the requirement and not the way to automate the script. Or we can find this by opening the file in SharePoint and looking at the address bar – the URL will have a sourcedoc=%7B{sourceDocId}%7D clause. But how to get that URL from the file?

Can you please look into the issue and help?
