Lightroom mobile trial (how to end)

Hi, I installed the adobe creative cloud app on my phone and using the app, I opened the free lightroom mobile app. While using the free Lightroom app, I suddenly saw that a trial activated by itself. I did not intentionally want to apply for the trial. My questions are:

1.) Can I cancel the Lightroom trial? If yes, how do I cancel it?

2.) Is Adobe going to charge me after the trial date ends?

Please help me. Thank you!
