I've been flirting with a girl a lot recently and I think I've found a perfect opening to ask her out smoothly. The problem is that my text game sucks ass. Recommendations?

Here's the convo we just had:

Her: I figured out the Google doc thing!! (in reference to something she mentioned about school when I was with her at bars last night)

Me: lol you're welcome. Tbh I half expected you to panic text me sometime today

Her: Hahahaha well I might need to panic text you to download it to pdf to submit. Can I still do that??

I feel like I can use this thread to smoothly and naturally transition into asking her out but I just can't find a way to word my text. My plan is to grab food/drink with her a nearby bar that she hasn't been to but wants to check it out sometime (I heard her say this to a friend in passing last night at bars)
