How can I do this?

We're very good friends and almost like best friends. I find her very pretty and I could imagine more with her. She broke up recently and said that she doesn't want a boyfriend for now, but if something happens, she will hardly say no. We want to meet after the Corona Kack and watch Netflix. She also thinks I'm pretty and I'm the only boy she's in contact with. But how can I proceed now (slowly at first) so maybe what will become of it?

Talks on the phone, stays in touch, but doesn't always write

Netflix & 'Chill.
