This Shortcut is intended to be used in conjunction with the Accessibility Back Tap function. Assign the double or triple back-tap to this shortcut to easily toggle between Orientation Lock on and off.

Recommendation:
In the Personal Automations tab, set a pair of automations: one for when particular apps are opened and the other for when those same apps are closed. These automations should unlock and lock the orientation, respectively. For best synergy, use the Orientation Lock Off shortcut instead of using a simple Orientation Lock action.
