Hashtag doesn’t display results…

I am trying to use hashtag #superherocapes (https://www.instagram.com/explore/tags/superherocapes/)

for one of my products… (a superhero cape)

below the product.. I am getting no results found. Does it only display from the hashtag on my personal feed? I want to display all results from a hashtag across the entire instagram app.. not just my feed.

Will this work? How do I fix?
