Ok. So you have to use ui interaction - click.
And then there are few options from there - either by text (you select what word should be clicked) but it might not be recognized in some cases or x,y coordinates (you would have to enable developers settings in your phone first, then pointer location - you would have to check on the internet how to do it, its easy but it might be slightly different for each device).
If what you need to click is already visible after opening browser it shouldn't be that hard.
