[FR] add intent additional to the "Assistant" stuff

sometimes it can be useful for automation and special cases.
(my case is that I failed to get screenshots on Android 6 AOSP, using https://f-droid.org/en/packages/io.github.sds100.keymapper/)
Can help?

Start by tracing the Android Assistant integration and screenshot flow on Android 6 AOSP, using the linked Key Mapper case as context. Clarify which additional intent and automation behavior is required; done means the requested intent works for the stated special case and is verified appropriately.
