As mentioned in the comments of the sample environment file, there are three permission groups that you can edit in the environment (.env) file. ADMIN_ROLES are roles that allow users to use /system and /mod commands. GPT_ROLES are roles that allow users to use /gpt commands, and DALLE_ROLES are roles that allow users to use /dalle commands. TRANSLATE_ROLES allows users to use translation, INDEX_ROLES allow users to use custom indexing commands, and SEARCH_ROLES allows users to use the search functionality.

If for a command group you want everybody to be able to use those commands, just don't include the relevant line in the .env file. For example, if you want everyone to be able to use GPT commands, you can just omit the GPT_ROLES="...." line.
