SUMMARY
I try to add an external tool call using the external tools plugin which requests an additional input parameter. My approach is to call a JavaScript window.prompt() function with the %{JS:} token, and I realized calling a JS function crashes Kate

STEPS TO REPRODUCE
1. Enable External tools
2. Create a new tool, for example:
   Executable: bash
   Arguments: -c echo "Input: '%{JS:editor.clipboardText()}"'
3. Run the new tool you created in step 2

OBSERVED RESULT
Crash

EXPECTED RESULT
Execute the tool as requested

SOFTWARE/OS VERSIONS
Kate version: 22.11.70
Linux/KDE Plasma: Ubuntu 22.04.1 LTS
KDE Plasma Version: 
KDE Frameworks Version: 5.100.0
Qt Version: 5.15.3
