Rotate camera smoothly 90 degrees on InputAction

I am trying to get the camera to rotate 90 degrees smoothly when I press an InputAction. I can get it to rotate 90 degrees and it works fine but it is instant. I found Rinterp to node while googling but I can’t get it to work. I’m still relatively new so I might be going by this completely wrong but I can’t seem to find much information about it.

The issue is that any interpretation speed less than 90 leads to that many degrees rotation (if I set it to 15 it rotates 15 degrees) and if I set it to 90 or higher it rotates 90 degrees instantly.

I think you could use a timeline.

Try using clamps?
