How to launch a new termx session from another termux session with activity manager

[ioogithub]

Termux has an excellent multi session feature. It is possible to open a new session by swiping from the left and selecting 'New Session' however I would like to automate it with a script. I am trying to use the activity manager (am) to launch a termux failsafe session from a bash script running in another termux session.

This code:
am start --user 0 -n com.termux/.app.TermuxActivity -a android.intent.action.RUN --ez com.termux.app.failsafe_session true --es com.termux.RUN_COMMAND_SESSION_ACTION '0'

returns an error:

Warning: Activity not started, intent has been delivered to currently running top-most instance.

According to the WIKI:
https://github.com/termux/termux-app/wiki/RUN_COMMAND-Intent#RUN_COMMAND-Intent-Command-Extras
there is a command extra that seems like it should work:

RUN_COMMAND_SERVICE.EXTRA_SESSION_ACTION extra for for session action of foreground commands. This defaults to TERMUX_SERVICE.VALUE_EXTRA_SESSION_ACTION_SWITCH_TO_NEW_SESSION_AND_OPEN_ACTIVITY.

How can I integrate this into my am command with the correct syntax? I tried variations on this but none of them work:

`am start --user 0 -n com.termux/.app.TermuxActivity
-a android.intent.action.RUN
--ez com.termux.app.failsafe_session true
--es com.termux.RUN_COMMAND_SESSION_ACTION '0'
--es com.termux.RUN_COMMAND_SERVICE.EXTRA_SESSION_ACTION 'TERMUX_SERVICE.VALUE_EXTRA_SESSION_ACTION_SWITCH_TO_NEW_SESSION_AND_OPEN_ACTIVITY''

If running inside termux app context: am startservice -n com.termux/.app.TermuxService -a com.termux.service_execute --ez com.termux.app.failsafe_session true

TermuxActivity, TermuxService and RunCommandService all have their own unique actions and extra key names, you can't mix them. Only com.termux.app.failsafe_session one is shared between TermuxActivity and TermuxService due to legacy reasons.
