I would like to create a custom dashboard with all cross information in context of specific user. I would like to give my support team ability to filter all data from APM, and Browser via specific user_id attribute. In APM I have this attribute now, and I can filter all the data from this module. Do I have to add this attribute also as a custom browser attribute to filter Browser data (page views, js errors, etc.), or there is other way to connect apm, and browser transactions by attribute?
