Trying to extract activity for team performance analysis via Oauth

[James Hartwright]

We're using Oauth to extract JIRA and confluence activity, but can't extract email addresses to tie the accountID activity back to the person (since the Oauth needs every individual to opt-in to exposing their email address). 

Our JIRA is all internal access only, so we could ask each individual to do it, but that's painful...

Is there?:

1. an easy way to opt-in to email share
2. away to get the email address to accountID linkage via the Oauth connectors?
3. another recommended method that's not manual (e.g. manual query and extract, adding an admin user and using REST APIs, JWT)?
4. something else I haven't considered
