Is MAC Fix+ Plus a setting spray?

Could you please clarify whether MAC Fix+ Plus is intended to be used as a setting spray? I've noticed it's marketed as a product that can help with makeup longevity, but I'm curious if it specifically falls under the category of a setting spray. Additionally, how does it compare to other setting sprays in terms of its formula, effectiveness, and overall performance? Is there a specific makeup look or occasion that MAC Fix+ Plus is particularly well-suited for?
