💡How does it work?

Code Explanation

The code above allows for the use of / commands and text based commands by the hybrid decorator (the @hybrid_commands.command) it then sends a "Welcome" embed and adds a drop down menu with the possible selections based off of a key pair in a dictionary! The key pairs in the dictionary are then pre-filled with the information from the rulebook and populated onto a new embed and sent to the user!
