Product Tab Vendor Side

I created a new product tab as admin (with a simple HTML block inside).


As admin, I can access that product tab, which is fine (can be accessed via the "product tabs" tab).


But as vendor, I am not able to access the new tab. And of course the vendors should be able to enter data into this tab....

Can someone shed light please ?

Thank you very much
