It’s okay
To everyone saying you can’t delete off of any iPhone:
Step 1 go to settings
Step 2 scroll and click on general
Step 3 click on iPhone storage and let it load
Step 4 there should be a little magnifying glass in the top right corner, click on that and search “reaction” and it should pop up. Click on that.
Step 4 hit delete, voila it’s gone. You’re welcome.
