Velocity only kicks the player if you have a client with version 1.19.1 or higher and with a valid signed key (this was done because Mojang implemented the reporting system from version 1.19.1 onwards and made it more difficult to cancel or modify commands and chat from the proxy)
If you want to prevent it from kicking, install SignedVelocity
