Smart Cover (only) for iPad Pro m4 13" (i.e. for the lightest, most minimal iPad)?

Remember when iPads had the Smart Cover--a magnetic, detachable cover without a back? Kind of like this version that Best Buy used to sell? I don't suppose any one has found one for the iPad Pro m4 13"?

Basically, I'm looking for the lightest, most minimal case and I figure something like that combined with a vinyl skin on the back would do the trick.

(Alternatively, I used to have a .35 mm plastic cover for the iPad mini. If anyone found a version for the iPad Pro m4 13", please let me know.)

Thank you!
