Mobile babies

Hi mommas, I need some advice. I’m slowly trying to get my 10 month old to sleep in her crib and while she sleeps there for naps and first few hours of the night, she always ends up in bed. Just decides to NOT be put down without me next to her. I know she wants more space because nights are dreadful atm and she complains and whines a lot. Now the problem is, due to bedsharing since birth she can’t self sooth to sleep and now she’s standing and walking. How do I sleep train her when I put her down drowsy and she just gets up and stands in the crib?? How to sleep train a mobile baby?
