What does this mean on Facebook messenger?

[indigo277]

Hi what do these three symbols mean next to a message that's been sent on Facebook messenger?

The smiley face lets you add a reaction - like a thumbs up, or heart, or sad face.

The arrow I think is "reply with quote" where you reply and include the original message. Handy if you're replying to a message further back in the chat.

The dots probably open a menu with more options.
