Difference between Microsoft Teams New Chat and New Chat Message triggers for monitoring messages

I'm evaluating the Microsoft Teams integration for a client project. The docs list 2 chat triggers: "New Chat" ("Triggers when a new chat message is received in Microsoft Teams") and "New Chat Message" ("Trigger when new messages are received in a selected Microsoft Teams chat"). Does the "New Chat" trigger monitor ALL incoming chat messages across all conversations for the authenticated user—similar to how the Outlook "Email Received" trigger monitors an entire inbox? Or does it also require selecting a specific chat? This distinction matters for our use case where a user receives messages from multiple different senders via separate 1:1 chats. Thank you!
