I'm not aware of any restriction on 360 videos in the trial version, but it won't let you import
any 2K (or higher) clips, or clips that are encoded in HEVC/H.265. In other words, HD AVC/H.264 clips, even 360 degree ones, should work.
As to your main question, I'm not 100% clear on what mode your final video will be produced in.
If it's true 360 - where the user has full control over direction and zoom - then you can't track the viewer position unless you break the clip up into separate sections and set a new starting view on each one. See this post for more
details. You
can however, add a motion tracked title or object to follow that person
around.
On the other hand, if you're going to produce a "flat" (standard) video from your 360 source, then you absolutely can follow the person around and even zoom in or out at will, as described
here.
