Vibrate pattern for messenger LG V20?

[AC Question]

I have an LG V20 and I can't figure out how to change the vibrate pattern when I get text messages. Tried setting it for individual contacts but that doesn't work. The only setting in the messenger app is just on or off. Also the phone settings only include calls and alarm pattern options, not texts. Anyone know about this?

that may be an app dependent setting. textra allows me to change the vibration pattern, but not for specific contacts.
