XF 2.2 Install App Not Working?

I noticed that my forum offers a button in the navigational menu that says, "Install the app [Install]". When I attempt to click the install button, it highlights the button but nothing happens. What can I do to fix this or remove it altogether?

It confused me at first. The install button does not start an install but it does start (In the background) a little video on how to set up pwa.
