Third party plug-ins with the option "Enable protected mode at startup" selectd.

I am the developer of a third party plugin and facing the issue of loading third party plugins into acrobat when the option "Enable Protected Mode at startup" is checked.    Can you tell me what changes are required for plugin application to load with protected mode.   Can you please tell me where can I find the example for such a plugin in acrobat SDK,  I searched the whole sdk(Acrobat SDK 2021), but couldn't find anything related to that.   Please help me to find it.

your help would be highly appreciated.
