Python Permission Problem

Trying to code a Discord Bot rn and already added the neccessary commands but instead of / commands I just use a prefix (?) as a command. Now the problem is everybody in my server can just type in the command and the bot responds to it, but I only want admins to be able to run the bot commands. Does this work with prefix commands or do I gotta swith to / ? 🙏 Thankful for any support
