Details of options payload for samlp connection strategy

Hi All,
I am looking into connection ( and connection.options) payload to see if all our supported SAML attributes and settings can be replicated in a connection. This is required for the proxy approach to work.

For this, I could not find references for flags such as checkAudience, checkRecipient, checkDestination which I used for POC (some others I got in this thread).

Can I get the complete options payload with their functionality?
