Get the email of current session logged in user (DOM Object?)

Development
#1

Hello,
When login to grafana, We use username: email@address.com
We are trying to get the user email address in the plugin, When calling
__$user we see its only a User ID.

Is the logged in grafana user kept somewhere on the DOM?

#2

${__user.email} will give you the user email as referred in the the link below.

#3

Do you know how to get it on earlier versions? on 7.2.1?
__user.email was introduced on 7.4

Thank you very much for the help!
