Apple Watch Only - How do you disable #images from Messaging App?

My kids have Apple Watches for emergency use and also quick communication with their parents. The problem is the messaging app has the gif search #images that I cannot for the life of me figure out how to disable it even on my own watch. They are able to search for inappropriate content potentially on #images.

My question is, how do you disable #images (the gif search) on the Apple Watch? Please don't send me instructions how to do it on the iPhone or iPad because the process is not the same, the options are just not there because it's not standardized across the platforms (iOS and WatchOS).
