Removing recent groups from messages

In ios 13 how do i remove groups of contacts from prior group message in text messages?

prior to 13 would start a message with each letter of the alphabet and look for contacts with the "i" symbol to the right. If you tapped on that, you would see the option to "Remove from recents." Tap it and it was gone.

In 13 it’s giving me a right facing arrow, which opens to a drop down then the “i” but no option to remove. HELP
