Seeking Advice: Using Arms Up Swaddle with Snoo

Hello! FTM mom here. My 1 month old really likes the Snoo but we noticed that she would fight the swaddle with her arms and cry when we would put her down (even if already asleep). On a whim we left her arms out and she fell back asleep right away with her arms up and stayed that way.

I've heard of others using and arms up swaddle in the Snoo and we'd like to try it but are unsure of the logistics of using that swaddle in conjunction with the Snoo swaddle. Has anyone had experience with this? Also, how do you ensure your baby does not get too warm? Currently we have her in cotton/bamboo footie pajamas and the Snoo swaddle and that seems to be a good sleeping temp for her. Our daughter definitely prefers the room to be cooler so we want to ensure she doesn't overheat.

Thank you in advance!
