Does Shar have a stake in the Blood War?

I am currently playing a character in Descent into Avernus who worships Shar.

While my character has their own goals, I’m trying to learn more lore about Shar’s dealings with devils and demons and if she has any skin in the Blood War.

The only thing I’ve found is a reference to her and Selune bringing order from chaos, but that’s neither confirmed not potentially relevant 🙂
