Help with swaddling transition

Our LO turned 3 months yesterday and has been swaddled to sleep since she was first born. She typically sleeps from 9pm-6am in her Halo sleep sack barely stirring or making a peep. (Yes we are lucky, I know!) I’ve noticed in the last week or so she is really starting to be able to wiggle her way out of the sack and once even pulled it up over her face 😳 It seems like it’s time to transition to at least having her arms out, but I tried that the last two nights and she woke up crying every 30 minutes. I’ve also tried swaddling her with her hands to her face, but she hates it and won’t fall asleep. A friend suggested the Zippadee sack, but I’m wondering if there is a way to transition her without having to purchase something additional.
