Getting baby to sleep in his bassinet

Does anyone know any methods that worked for you? My son is 7 weeks old and we bedshare. I’m fine with it because it’s easier for bf but I’m really missing getting to snuggle with my husband and have my own space. He has never wanted to sleep in his bassinet and wakes up every time I put him in it. He normally sleeps really well at night, only waking up once to eat.

How can I get him to start sleeping in his bassinet?
