Ring sling

I purchased a maya wrap ring sling. I am finding it hard to get the hang of it. My baby is just over 7 weeks old and I can't figure out how to put her feet in comfortable. Every time I try to use it I find the fabric gets all bunched up in the rings. Any tips or tricks you can give me on how my baby's feet are suppose to go in and how to use it in general? I've watched multiple YouTube videos on it and I still can't seem to get it right
