Your ame can add items you forgot. And your ame has to explain to the faa what 'prnc' means with a brief summary - which I ask applicant to provide, instead of prnc.
most of the time the HIMS FAA requirements are of a weekly facilitated group meeting. Facilitated mean a lead by a licensed mental or substance-abuse counselor. This is not an AA meeting. Sometimes it’s called relapse prevention meetings.
though I have not seen the FAA ltr instructing such, I suspect they are requiring 'group facilitated' meeting ... sometimes call relapse prevention groups.
