Documentation for command arguments is missing

[Sirius-KiH]

The documentation on command arguments is empty:

https://github.com/mautrix/docs/blob/master/maubot/dev/handlers/commands/arguments.md

[MoralCode]

Someone else also reported this at https://github.com/maubot/maubot/issues/203 Would be nice to know how to do commands with multiple arguments
