newborn hates bassinet

My 19 day old has the halo bassinet and hates it. I get that they say to sleep on flat and that’s why we have this but she hates it. This is our first, we have her sleep here all night but she definitely prefers sleeping in her bouncer or swing but we don’t let her except for supervised naps. Anyone else have the halo bassinet and also find there babe doesn’t like it? What did you do? I heard there is a newborn insert but don’t know if I like the idea of adding something to it. I’m going on one hour of sleep here and am exhausted.
