Possible to find out where feature layers are being used in web applications?

[ZachRobinson_SantaClaraCounty]

I am wondering if it is possible to easily find out which web applications in our ArcGIS Online organization are using a specific feature layer.

For example, if I delete a layer from our organization, I want to make sure I know which web maps and applications the deletion will affect. This can be difficult and tedious to search manually when an organization has many web maps and applications.

@lxk1170 do you have any idea how to implement this with SAML authentication?

See my code above this post. We use SAML and it works for me. Good luck!
