What app is this chat icon from?

Hi all, I've been trying to identify what app this chat icon (outlined in red) is from. It's a screenshot from a Samsung phone in the USA. It's not the native Samsung or Google messages app. It has a right facing arrow inside of a speech bubble. I've tried googling but only come up with stock images for app developers. This is from a screenshot I received so I can't go into the phone and see what the notification is from. Anyone have any idea?
