C200: CN-E lenses on EOS R5

I use the CN-E 18-80mm and CN-E 70-200mm on the C200. I tried both lenses on the EOS R5 using the EF-RF adapter. I noticed that AF did not work for these lenses both in full frame and crop mode. I suppose this is normal behavior, that is, EF cinema lenses are not fully compatible with the EOS R5. Do you have the same experience?
 
Is the R5 able to provide them with (enough) power for the servo’s? Are they otherwise detected/recognized by the camera?
 
That's how it was with the 5D Mark IV, so I'm assuming nothing has changed and you still need a cinema camera for full compatibility.
 
I had set the servo to "manual" on the lens. After switching on the EOS R5 it displays "Manual Focus" on the LCD screen for 2 seconds. So it looks like the camera recognizes a non-AF compatible lens. In the official EOS R5 specs on Canon's website EF cinema lenses are not listed under compatible lenses. For the C70 (also RF mount) EF cinema lenses are explicitly mentioned, but that is a super35mm cinema camera.
