Applying Effects that take parameters using UXP

I have been able to successfully apply an effect like "AE.ADBE Invert" to a video using UXP. But there seems to be no way to add parameters to an effect like  "AE.ADBE Lumetri" which takes multiple parameters. How to query and add parameters? I have checked the github samples and that was not helpful - am I missing something?

Any clarifications or pointers on how this can be done would be greatly appreciated!
