UXP: Show Clip Keyframes for Selected Clips

I'm trying to write a simple plugin that allows me to change the shown clip keyframes of the selected clips from opacity to time remapping -> speed. I can't seem to find access to that variable in the UXP documentation, but it would be greatly helpful.

I guess this would also be an idea/request to allow for changing the shown clip keyframes within a multi-clip selection. This would significantly speed up my workflow and the workflow of just about every other editor that I'm in contact with.
