Pause Octoprint for filament change?

Hi
I have a X-max and since some days connected via the usb TTL with an RPI4.
The first prints are working good.
Also on the RPI there is a filament sensor connected.

The Idea know is, that if the filament sensors throws an error, that the printer would react as the print was paused for a filament change.

For my understanding what I need:
Gcode for:

• save last printing position
• stop extruder
• cool down extruder
• move into a filamen change position

Then I would do the filament change via the Printer Touch

and after the change the gcode for the resume:

• resume print

Thanks in advance
