Is there a way to interact with the Approbations app other than from Teams and Power Automate ?

Hello,

I would like to know if there is a way to interact with the Approbations app in Teams: 

By interacting, I mean performing operations through APIs, SDKs, etc. The interactions I know of are from Teams itself and Power Automate predefined actions.

My need is to be able to customize the app to receive input from other sources.

Thank you for taking the time to read my post and your answer as well as your opinion is welcome .
