Hi
I try adding structured data to my app to improve SEO. I took the following steps, but did not succeed:
1- Added the structured data script to the header of the homepage.
2- Checked if application/ld+json is in the Page Source → 
3- Used https://search.google.com/test/rich-results to test → 
“No rich results detected in this URL”
Would someone be able to help me with this?
