Adding Proficiency to a Skill in a Magic Item

[PhilFischer]

I would like to add a Skill Proficiency to a Wondrous Magic item.
I have tried various things, but haven't found how to do it in script yet.

I did see some races (or subrace, not sure where) that added the skills in the Tags area but of course this is a magic item.
[NOTE: would adding skill proficiency to a template work like that? or how would I add skill proficiency to a template?]

I also saw where they added an armor proficiency to a Tag, and then in code (script) had the line:

~ Give proficiency with heavy armor
perform hero.pushtags[ArmProfGrp.?]

Is there a way to do it by pushing the tags I set in my magic item, i.e.:

~ Give proficiency with skill proficiency
perform hero.pushtags[SkillProfGrp.?]

or some such thing? (SkillProfGrp does not exist that I know of)

From the github repository:

To grant proficiency to an armor group:

perform hero.assign[ArmProfGrp.ArmorLight]
perform hero.assign[ArmProfGrp.Shields]

To grant proficiency is a saving throw:

perform hero.pushtags[ProfSave.?]

To grant proficiency is a weapon:

perform hero.pushtags[WepProf.?]

To grant proficiency with a skill:

perform hero.assign[ProfSkill.skSleight]

To grant proficiency with a Tool:
