Teams Shared Channel is Missing the "Make this a Tab" button

[DMark2000]

I see the "Make this a Tab" button in the Files section of Standard and Private channels, but I do not see this button in Shared channels.  Is this a known limitation or a forthcoming feature?

Hello
I do see the same in my Shared Channels, it is probably not currently possible to add a document as a tab. I'll try to find out if this is planned to be available.

Thank you Sir. If you hear anything I'd be interested in knowing if there is a plan.

I'd also like to know if this feature is on the horizon
