problem with unhiding tabs

I have multiple tabs of same session opened and I tried to hide some. I am on 2023.2.17.0 .
When I tried to unhide the hidden tabs I didn't know where to do so.
The only place I could find that seems to unhide tabs is to right-click on the session and choose 'unhide'. However, this only works if I am hiding a single tab because this action restores a single hidden tab only and the option of 'unhide' then disappears.
I ended up with multiple tabs hidden while I am not able to unhide them.

I can see hidden tabs in 'Window' menu. however, if I click on hidden tab it doesn't get restored.
It seems I can only hide a single opened tab from a specific session. if I hide multiple tabs, I can restore only one and others get black-holed.
