Need Advice about my 9m baby

My daughter just recently started rolling from back to belly at night... She can't roll herself onto her back... She fusses and doesn't seem to try to roll back... She did it randomly for some weeks now, but not consistently enough... Should I just let her figure it out? It happens at night recently after ours later, r putting her down.

What should I do to help her better at this? She hates belly time still... I do have her do it, but not as often as should.
