Connection string for a successful SSMS connection

In SSMS v19 I can successfully connect/login to a SQL server that is listening on the default port 1433 Server : server.env.domain.com,1433 Authentication : SQL Auth And I can query any of the databases hosted on this server. Does SSMS reveal the connection-string it is using to make this connection ? I've searched quite a bit and can't find it. Or is there an API I can call that would return the exact connection string used by SSMS ? I ask because I am unable to connect via another app located on the same client machine as SSMS. I would like to know exactly how SSMS is making its connection.
