The method "inbox" is related to everything that happens in direct messages with the bot. You can fetch conversations, messages, and leave a conversation.
To access the inbox object, you can utilize the Highrise class instance. For example, if your instance is named "bot," you can call the inbox method using bot.inbox. Any subsequent method invoked belongs to the inbox. For instance, bot.inbox.conversations.get().
Note: If this is too complicated for you, please feel free to ask in Highrise's Discord bot-api channel.
