How can I get the insights corresponding to each optimization goal with the Meta API?

Question

I wish to get insights which correspond to each optimization goal - for example, {'OPTIMIZATION_GOAL':['KPI1', 'KPI2', ...]}.

However, this is proving difficult, since certain optimization goals (such as VISIT_INSTAGRAM_PROFILE) seemingly cannot be fetched via the Meta API, and certain others are confusing as to which KPIs correspond to them. That said, I noticed that the parameter can indeed be seen on the Ads Manager, under 'Results':

Screenshot of Ads Manager, showing number of Instagram profile visits for a campaign containing two ad sets with VISIT_INSTAGRAM_PROFILE as their optimization goal under the 'Results' column.

Is their a way to access this results parameter? Even better, is their a page on Meta's API that I haven't been able to find which points to an optimization_goal/insight mapping?

I've explored the documentation in the insights page, the Action Stats page, and the Ad Sets page, but VISIT-INSTAGRAM-PROFILE remains elusive. I'd appreciate a way to solve this without manually analyzing which KPIs correspond to each optimization-goal.
