Add-Debugger

The script adds or replaces existing debugger in any runspace. It is
useful for hosts with no own debuggers, e.g. 'Default Host', 'Package
Manager Host', 'FarHost'. Or it may replace existing debuggers, e.g.
in "ConsoleHost".

The script is called at any moment when debugging is needed. To restore
the original debuggers, invoke Restore-Debugger defined by Add-Debugger.

Console like hosts include 'ConsoleHost', 'Visual Studio Code Host',
'Package Manager Host'. They imply using Read-Host and Write-Host by
default. Other hosts use GUI input box and output file watching.
