Expose Mask API in the Premiere Pro UXP SDK

I'd like to request that Adobe expose mask manipulation through the Premiere Pro UXP API.

Currently developers can work with sequences, clips, markers, and many timeline operations, but there is no public API for accessing or editing masks attached to clips or effects.

It would be extremely valuable if the API allowed developers to:

Read all masks
Create new masks
Duplicate existing masks
Delete masks
Move masks from effect to another or from unassigned masks to an effect

      Hello Ghxst_Dz,

      Mask data isn’t stored in any share-able format; if it were, what would you like to do with that mask data? 

      How do you imagine programmatic mask creation would work? [If you’re creating it via API, you’re creating it without user interaction...]

      If you’re planning to move masks from one trackItem to another (I’m not sure what an unassigned mask would even mean, in Premiere), it sounds like you’re on your way to inventing After Effects. ;)

      More details on the workflows you’d like to enable/support, beyond basic CRUD functionality, might help make the case for prioritizing such work.
