Hello Everyone, I'm asking for any suggestions about an issue I have with our web app and its Laserfiche integration. For context, my current authentication configuration uses LFDS and SAML with Azure. Right now, if I want to open a document from one of my repositories, I get the SSO page with the blue SAML login button. Once I press that, I get my document. What is really nice is that both Edge and Chrome seem to store my Azure account so I'm not typing in my email and password. 
What I'm looking for is a way for my web app to tell me if someone's account is set up with a LF license before they have to press the SAML button. 
The browsers know what account is already signed in, so I was wondering if anyone knows of a way that I could use that information in the browser to return a message to my web app that a user does not have an LF license before they try to authenticate. Is there an API or something I could build into my web app that would display the account signed in as well? If I was able to get that information before they were prompted to sign in, I could then tell my users that they won't get in and reach out to my support team. 
I'm thinking something like what you see in the corner of office apps. It tells you what account is logged in. If I could get that information myself, I could use it to query LFDS and check their account before signing in to LF. 
Thank you for any help or direction you can provide!
