Which keyboard for iPad 6th generation?

My old Logitech Slim Folio keyboard is falling apart and needs replaced. I bought a Logitech Slim Combo online, in perfect condition, specifically for 5th and 6th generation iPads, but it refuses to connect. I have tried everything suggested by online forums but it just won't connect.

My iPad is up to date with IOS 17.7.6 so it may be a software issue.

Can you suggest another keyboard?
