Hi @Ampere -- I figured it would be easier, and faster, to put a quick video together for you...
let me know if this answers your questions!
I just had chance to sit down and actually try this for myself and make the plan to implement this.
I just wanted to mention that when I followed your video to find my own Share URL, it shows as the newer g.page link, but with a ?share at the end: g.page/MyCompany?share
I noticed that in your video your Share URL was a goo.gl link, so I figured maybe you would be interested in the change.
