Tips to get baby sleeping in bassinet?

We have baby’s bassinet in our room but he won’t go down in it. I’ve literally tried everything I can think of. I put him down, he either cries right away or 3-5 minutes after he’s put down. I try to get him to sleep without picking him up. After the 4th time though I end up just putting him on my chest and let him sleep there (passes out immediately). I think he’s much more comfortable on his belly, but too young still for me to put him down that way. He’s 5 weeks old and I realllllly want him sleeping in his bassinet. I’ve tried so many different things. Any other tips on how you’ve been successful would be appreciated!!

-swaddled (arms down at side, hands close to face, arms out)

-love to dream sleep swaddle

-put down drowsy/half asleep

-put down deep sleep, limbs hanging

-tapping belly/bottom/back

-hot water bottle to warm up bassinet before putting him in

-towels under mattress so that it’s raised a little on the sides

-pacifier

-holding him out over the bassinet (not against my body) so he adjusts to the new environment

-white noise machine
