Hello, I try to make and run phone automation shell scripts.

Tech info: Samsung Note 10 with Android 12, rooted with Magisk.

After rooting my phone my scenario is as follow:
Step 1:
I wrote simple Magisk module Run_external_script in which action.sh invoke sh "/sdcard/Documents/installation_automation_magisk.sh" ← this work fine;

Step 2:
In script installation_automation_magisk.sh I install few Magisk .zip modules and few .apks (e.g. termux.apk, termux-api.apk, termux-gui.apk) ← this work fine and all is installed correctly.

Step 3:
At the end of installation_automation_magisk.sh (run by minimal shell from Magisk module) I want to call more "rich" /sdcard/Documents/installation_automation2_bash.shbash script in Termux (to install .deb packages, display GUI, etc.). But it seems that calling command by intent doesn't work - it just open Termux console window as it would be launch from app drawer.
With one whole day writing with GPT I don't found any solution.
To troubleshoot a problem I try to call even simpler intent:

  -n com.termux/.app.TermuxActivity \
  --es com.termux.RUN_COMMAND_PATH "/data/data/com.termux/files/usr/bin/bash" \
  --es com.termux.RUN_COMMAND_ARGUMENTS "-c 'echo Termux is ready!; sleep 3; echo Pause complete'" \
  --es com.termux.RUN_COMMAND_WORKDIR "/data/data/com.termux/files/home" \
  --ez com.termux.RUN_COMMAND_BACKGROUND false

I tried all variants: call directly ...RUN_COMMAND_PATH "/data/data/com.termux/files/usr/bin/echo", only one command like ...RUN_COMMAND_ARGUMENTS "-c 'echo "Hello Termux"', run in background true, opening Termux app prior and then after 10 secs sleep run intent, etc. etc. etc. - all GPT's ideas.
Of course calling intent with bash command and script installation_automation2_bash.sh as argument didn't work too. Above commands show that any, even echo or sleep commands are not executed by calling intent.

Always result is like I would just open Termux app and there are just welcome texts in console, and any command from intent arguments aren't running.

This code snippet from RUN_COMMAND docs didn't get any output too, just opens Termux window.

What I doing wrong?
