According to the Logitech website, as already mentioned by Marcosalonso:

Detachable keyboard case with backlight, trackpad and Smart Connector for iPad Pro 12.9" (5th and 6th generation), iPad Pro 11" (1st, 2nd, 3rd and 4th generation) and iPad Air (4th and 5th generation).

Please confirm.

Best thanks.

According to Apple, the two models have the same dimensions. On the Logitec website, this product is offered for both Gen5 and Gen6 IPads.
So I strongly believe that it is 100% compatible.

Can someone from @Digitec please confirm this and add to the product description?

Hello, no I don't think so.
