I'm using Geyser as well as Flootgate as a dependency library development.

FloodgateApi Fapi = FloodgateApi.getInstance();
ProxiedPlayer Pplayer = (ProxiedPlayer) commandSender;
UUID senderUUID = Pplayer.getUniqueId();
boolean isBEPlayer = Fapi.isFloodgatePlayer(senderUUID);
SimpleForm.Builder CForm = SimpleForm.builder()
                .title("A").content("B");
CForm = CForm.responseHandler((arg0) -> {
                System.out.println(arg0);
            });
            Fapi.sendForm(senderUUID, CForm);

This is a duplicate of #178 and unfortunately we don't really have a solution for that yet.

https://github.com/kejonaMC/Floodgate You can use this fork of floodgate which solves this issue :) do know that this is a fork and not a release from GeyserMC
