When a fast pair provider (accessory) is ready for pairing, it advertises a payload that indicates Google Fast Pair Service. At the same time, the fast pair seeker that will periodically scan for a fast pair provider and will observe the advertising frame and takes action, if requires.

How To Get Google Fast Pair Service?
