I 22m likes a girl from my office 22F please any advice on how to approach her

To give you guys an overview. We both are in the same company. Both of us were in company training and I started earlier than her so it makes me her senior I have finished my training and I'm in projects and all, she still has 1 month of training and then she will be transferred to another according to what I have heard.

I want to say directly to her that i like you and all but the fear of POSH stops me. So now I want to talk to her so that we can know each other more but that's also becoming more and more difficult to do.

I usually meet her during lunch for 5 mins she doesn't know that I deliberately take a break during that to meet her and since last 2-3 days I have been very busy and unable to meet her and all.

Also I have become a very hot topic in her training group not sure if it's good or bad. But I find it a little uncomfortable..

Yesterday one of my office colleagues told me like she came to the pantry and according to him she was looking for me.

I don't have her insta but I do have her linkedin.

And then I have also once messaged her on WhatsApp but it was a very short conversion about our office and nothing else.

One more thing there were some hints from her that she wants to talk with me but not sure whether they were really hints or not(I'm very bad at taking hints)

So any advice from you guys on how I should approach her and talk to her?
