Search then Click on Element

[maddire]

Hi, is there a method to Raise a click event of a Button based on the class and innerHTML of an element?

Example: I can navigate to the following URL: https://mega.nz/#!20pzDaAQ!dNuODm_0_SS1C...Gs2LfMmzUM

But I want to raise the Click event on the Download Button. 

IS this possible?
