my beautiful friend's angel lost at 36 weeks. how to truly be there?

Hello lovely people, I hope everybody is being kind to themselves today.

My best friend lost her angel daughter very recently at 36 weeks and left the hospital this morning, with an obviously shattered heart. She told me only a few days before, and since then I've been checking on her each day just to let her know I love her and am here if she needs any sort of help with her first child while her and her partner are coming to grips with everything. We've always said that I'm her little boy's and arriving baby girl's aunt and there are truly no words to describe the loss, but what really weighs on my chest is how truly beyond heartbroken she must feel.

I want to do anything I can to help her, but I don't want to be overbearing. She's understandably not as talkative as usual and I feel so lost. I know I can't fix the pain but I want to be there and maybe part of me wants to channel my own grief into being the invisible helper fairy. I've told her to let me know when she's ready to see people so I can come give her a hug, with no pressure whatsoever, but part of me feels like I should drop something off to make something in her life easier while she's grieving? Without going in or anything, I don't think she is in the place to be social. Is there anything anybody who has experienced something similar wished for when they first got home?

Thank you, and much love.
