Can my company track my web history when Opera VPN is active?

Today I brought my personal laptop to the office. My laptop connects to the personnel wi-fi automatically (not actual intranet). To mention, my work ID and password are needed to connect this network. I was working on Google Chrome and i wanted to look at something that is not work related, so i opened Opera Browser. And i saw that NSFW url on the tab (it was cached at home and it seems i forgot to close it) I closed the browser as i saw it even before any content was loaded. And now, i am worried about this situation.

The thing is, after i returned home, i opened Opera and i saw Opera VPN was active. And history was clean in working hours (Well, i can’t tell for sure because i am pretty worried so i can’t think straight. And i cleaned the whole history)

Long story short, it was a personal computer (not a work computer). It was on a company network with validation. Opera VPN was open.

1) Is it possible that my visit didn’t get logged in history as i mentioned above ? (due to fact that VPN was trying to start up and i closed the browser immediately)

2) Can Opera attempt to send that request without VPN as i open browser when VPN starts up?

3) Do you think it was logged by my employer?

4) What should i do in this situation? (It was a total mistake, i didn’t attempt to visit any NSFW website at work, i just forgot to close it and i didn’t stay there even a second. I even didn’t get to see if website was blocked or not)

P.S. I am working in a finance sector, so there is full security
