How often do you pull in other people?

I started a new role as a hyperscaler, I've done hands on work with AWS and GCP on and off for a couple years and have general familiarity with what I'm doing. But I have some customers that will want to go over hyper esoteric topics that sometimes even my senior specialists don't know. Therefore I find myself pulling people in constantly. I think part of this is just me being new (I'm like seven weeks into the role) but it's still different than selling single product SaaS like I did in the past, where I was essentially the specialist and rolling solo within two months.

I think this is just the nature of the beast and no one knows everything, you have to play as a team. The SEs job in these situations is more to corral the specialists and make sure the deal progresses, make sure the POC is well managed rather than know literally everything because that's impossible.

I'm still used to selling simpler SaaS that an SE can solo, I've been doing a lot of cloud development on my own but it's primarily with a specific niche of services and using Python. Any thoughts on this would be appreciated.
