Websockets || Multiple Send Messages

I'm trying to connect to the Polygion.io websocket for all trades. In order to connect, you need to send a message to authenticate:

{"action":"auth","params":"********"}

Then once you're authenticated, another to subscribe:

{"action":"subscribe","params":"T.*"}

From what I can tell, the open_message only sends one send request and there can't be multiple strings within the open_message. Any suggestions if this is possible, if not, is this something you'd be open to adding?

Start by reading the linked Polygon.io websocket documentation and locating the websocket input's open_message handling and send behavior. Determine how authentication followed by subscription messages should be represented, then verify that multiple messages can be sent in order for the reported workflow.
