there is no native intent to do that, its up to each app to provide its own services there. Sleep as android has a custom intent to enable/disable an alarm by its label but not remove it.
Every app is going to be different, the companion docs offer some live examples of Sleep as Android and Googles own apps. You’ll find links to the corresponding docs there too, outside of that its best to contact the app developer or look up their docs to see if they support it.
There is a thread that lists all the apps taht we have found to offer some type of example but largely if its not mentioned in the forums/docs you’ll need to do a bit of trial and error to get the command right. Its a bit of an advanced topic as some commands will require more trial and error than others, especially if you need to use a manifest reader to try and guess how things work.
