I have set up an RDS deployment exactly like its outlined on Microsoft documents, and tried to publish it with Azure AD Application Proxy. But all I receive is the IIS welcome page when browsing to the external url, so apparently I have not done something right. Does anyone have experience with this?

I don't understand the portion about common root. Both Web and Gateway are on the same server, and those roles were added through Server Manager on the connection broker.
Both the RD Web and RD Gateway endpoints must be located on the same machine, and with a common root.
