Edit: Shortly after making this post I found the answer. For anyone searching for the same thing, you just need to call
Code:
InterfaceOptionsFrame_OpenToCategory("ADDON NAME")
I made a panel and some options in the interface addon menu for my addon.
I can hit escape and access the addons menu from there, but I wanted to add a slash command to open up the menu automatically.
I've done this a long time ago and I forgot how I accomplished this. How would I open up the interface addon window and select a specific panel with LUA?
