Yes, you are correct. Please see codurly’s documentation for that:

Basically you need to create the bridge between phone and bubble, get the ID, give it to an element, then get it from that element into the database and assign it to the user 
And yes, you need the entire code from pastebin to paste it in your run this javascript workflow.
It’s a bit more than just click install and done but it will do the job. Once configured you will even forget about it.
@codurly maybe you can share those videos on something else so we can better understand what’s in them 
Thanks!
Here are the settings:
L.E. be sure that the javascripttobubble is on the page on which the user will be redirected after login! The user must be logged in in order for the entire system to work (you know…current user’s…)
Maybe this is a good chance to ask bubble (don’t know if they will see it but it’s worth a try) to change the text when we perform some changes on the app. Since we will going to use web views as native apps, the part where it says that we need to click there to refresh the PAGE. Could you please change that to… APP? Thank you in advance!
