According to this link, I can use another identity provider other than the out of the box providers like Active Directory, Google, Facebook. I have an IdentityServer4 hosted as a web app in azure and would like to add that as a custom Identity provider. But when going to the Authorization/Authentication blade of my mobile app service in azure portal, there is no option for a custom identity provider.
I can't find a tutorial in the web that allows you to add a custom Identity Provider. Note that I am looking on how to add a custom identity provider, not using a custom authentication logic which is documented in Azure. I will appreciate any help. Thank you.
