Godot + Postgres, PostgreSQL Client in GDScript problem

Hi, I try to use PostgreSQL Client in GDScript PostgreSQL Client in GDScript - Godot Asset Library. Does someone know what need to be added to this place?

If you CTRL click the problem function does it give you documentation on the parameters?

That line should be:

stream_peer_tls.connect_to_stream(peer,user_global)
