Remove certificates from iOS 15.4

I'm trying to figure out how to remove certificates from my phone. I'm unable to access the wifi network at my job because of an untrusted certificate. I've looked online for steps, but I don't see "Profile" under "Settings" and then "General." I'm guessing because I recently downloaded the new iOS 15.4.1 and perhaps the path has changed? Any help is much appreciated! I have an iPhone 12 Pro.
