Any one using the snuggle me organic?

My baby will not sleep in her bassinet, swaddled, not swaddled, dock a tot, occasionally will sleep next to me following the safe seven, but will only truly sleep on my chest and I wrap a light blanket around us tucked in under my sides so she won’t fall. I prop myself up so her head stays higher than her butt and we have an owlet but I don’t know how much more of this I can do. It seems she hates being flat on her back. Most times she can tolerate it but other times she gags, gulps, grunts and snorts and it wakes her up. She doesn’t seem to have any other signs of reflux. I’m just at a complete loss and want to just lay down and curl up in my bed 😫😫😫
