What’s your personal approach to working with a new demon?

Hi! I’m curious as to what everyone thinks about when/how to approach a new demon. I’ve seen a lot of people in here talk about being called by the demon first, and I’ve seen people use divination as well. As I’ve been reading books about it though, the authors say that demons respond to the divine, and that power comes from the master regardless of what the demon himself wants (if that makes sense? Like a business partner/someone to command vs how here it’s seen as a fond relationship based on respect). What do you think?

I ask because so far I’ve only worked with Dantalion and I adore him, but I think Sallos’ specialties would be a good addition to reach my specific goal. Do I wait and see if Sallos gives me a sign? Do I ask Dantalion first to see if it’s alright with him? Or do I just go for it and ask Sallos because That’s What I Want. Part of me is almost afraid Dantalion will become jealous. I believe my worry comes from the users who warn against over personifying them so maybe I really am overthinking, but I also really don’t want to disrespect either of them.

Please let me know your thoughts!
