TLDR: How do I escalate with a girl who seems to be undecided about me?

I'm talking with this girl and while its really slow going with a lot of mixed signals and back and forth push and pull from both sides I've reached the point where we have comfortably crossed the physical touch barrier (by her initiation) and ive also accepted it and tried to escalate from my side.

Issue is ive only recently started working on my inner game and confidence and have almost no experience with dating.

I'm not sure what the acceptable escalation steps are when it comes to kino. She already hits me when i tease her and tried to play footsie with me once.

She's told me she won't bite when i was hesitant about getting in her personal space and even since that ive tried my best to not be like that.

The other day i caught her hand and pulled her hand to take a look at her nails and another time for a new watch she was wearing.

But I'm not sure how to escalate from here. I don't think I can go for a kiss or anything yet because we are yet to go on a proper date ( long story but she turned me down with some shitty excuse and then when I ghosted her after that she reached out to talk and we got closer but still no date yet)

She's not had many relationships herself and mostly had 2 long relationships till now and i think she's casually talking to few people rn at best. She's definitely not serious with anyone else.

I feel like she's still evaluating me and it's partly my fault because early on i was coward and didn't flirt or escalate and killed her attraction but I'm trying to fix that now.

I really just want to escalate a bit to see if she's into it next time we are at a cafe 1:1 and if she is then I'll ask her out proper and be done with it either way.
