Applying Lightroom Presets to videos in Version3.4

Hello, I am trying to figure out how to add the bright preset that came with my app to my videos in the paid version 3.4. All the tutorials I see so far say to do it from a library option at the top and my screen doesn't look like that or have that option at the top or anywhere that I see. I would like to know how to do this in mobile and laptop. Thank you in advance!
