Pair programming is one of those things you hear about so often, but I've never worked somewhere where it was actually done.
Most devs, myself definitely included, don't wanna sit there with another one while they work on a single problem. We both have our own respective tickets to worry about, who's got time to split entirely dedicating to 1 ticket that isn't yours?
Instead if we hit a major roadblock we'll shoot out a message like "hey dude got a minute?" And hop on a huddle on slack, but I definitely wouldn't call that pair programming the way it's usually implied
