The data pack has a built-in menu for settings and debugging. You open it with a single command.

1. Make sure you can run commands. In a single-player world, cheats must be enabled. On a server you need operator permissions.

2. Open chat and type:

/function menu:bubblellaneous

3. Press Enter. The menu appears in chat.

4. Use the options it shows to change settings or run debug actions.

If the command says the function is unknown, the data pack is not loaded in this world. Run /datapack list and check that Bubblellaneous is listed as enabled. If you just added or enabled it, run /reload.
Type /function menu: and let the game's tab-completion suggest the rest. This confirms the pack is registered.
Use the menu first if something behaves oddly. It is the place the pack provides for troubleshooting.
Menu entries are usually clickable text in chat, so click them instead of typing.
