Looking for a way to know which staffer uses the app without the "read_users" scope

Hi everyone.

My understanding is that the “read_users” scope is only available for custom/private apps on Advanced plan or Shopify Plus stores. This is mentioned in the documentation for the user endpoint in REST,

However, in my situation, I’m not interested in any data from the staff members but I want to know on my app which member is currently using this app.

It may be a random ID without any info on the staffer, I just want to be able to customize the app dashboard so that every time someone opens his dashboard he should see the state where he left off.

I would love to hear if there is any workaround to make this happen.

Regards

Dave
