Recommendation for a foldable keyboard to use on a 2018 ipad running iPadOs

Hello,

I would like to know if anyone has good recommendations for a foldable keyboard for an iPad Pro 2018.

I already have a protection case for the iPad and I would like to find a foldable keyboard that could be charged using a USB-C cable.

Does anyone have experience with foldable keyboards? Are they as reliable as the usual keyboard?

I would like something similar to one of these except that it would need to be able to be charged using a USB-C cable:

 Also, I was wondering if the spacing between the two parts of the keyboard was something that would take some time to get used to as compared to classical keyboards?

Thank you in advance for your suggestions.

Best regards!
