Hi there,
So, this one is the easiest, main point is to have the website open, then connect the device and have it detect it when you connect. It’s always tricky the first time, from what I have seen here. BUT it does work well when you nail it down, This one is a good start
see which steps don’t work and report back, You get it going but it takes a bit of patients 
with all this stuff 
Also have a look at the post I made on it,(search icon) several options for the final result are possible Local vs. Online.
It is very powerful and somewhat cool too. Mixed with the inferencing it can give your project Vision
