Newborn won’t sleep anywhere else

So my newborn won’t sleep in her bassinet, I’ll put her in there and she’ll lay there for a few minutes then start moving all around then cry. She’ll only sleep in this “cuddle me” pad on my bed next to me. I’ve tried swaddling her in the bassinet and she freaks out she wants her arms free. I’ve read newborns should be sleeping on a firm flat surface so it makes me nervous she’ll only sleep in the cuddle me pad
