Thus Ráma spoke; and Lakshmaṇ taught In all the art that utters thought, To King Sugríva’s learned spy Thus made his eloquent reply: “Full well we know the gifts that grace Sugríva, lord of Vánar race, And hither turn our wandering feet That we that high-souled king may meet. So now our pleasant task shall be To do the words he speaks by thee.”

In plain words: Lakshman, also a skilled speaker, answers Hanuman. He says they already know of Sugriva's good qualities, came here to meet him, and will gladly do what Sugriva asks.
