Minecraft wiki entry for Emotes, associated text: It actually doesn't matter whether the player is submerged (partially or fully) in a liquid (water or lava), flying, falling, levitating, sneaking, or on dry land, just as long as the player isn't riding anything, the player would still perform the emote.
In the crossover fighting game Super Smash Bros. Ultimate, the simple clap emote is used for Steve's clap animation when he loses a battle or if a player resigns from a battle, resulting in a "No Contest" screen.
The "Celebrate" and "Follow Me" emotes were shown at MINECON Live 2019, but have not been made available.[2]
