QR Codes and Hubspot Tracking URLs for Places without Hubspot Tracking Code

Hey HubSpot Community!
I am facing tracking issues with a QR code leading to a Linked In Profile.
Let me describe the consideration briefly:
We would like to measure the engagement on the Linked In Profile from on of our Sales Reps.

In order to do so, I created a Tracking URL navigating to the Profil. In addition, I created a respective QR Code as another feature to measure the traffic.
However, everytime I or someone else scanned the QR code, nothing happend.

I read in another forum that this UTM has to be defined as Organic Social - which I did.
Another thing is how it relates to a campaign that I created. Regardless that no traffic could have been created, I cannot see how the URL Tracking belongs to the Campaign as there is no such asset to selet the URL Tracking. I know that I can create a tracking URL in the interface of the campaign but I does not show me the URL in the campaign itself.
In short, I would love to get your support to get this intersection of the QR Code from a LinkedIn Profile to my HubSpot URL Traking going - does somebody have a solution=
Thanks for reaching out.
Best,
FiRi
