How do I allow the Jira Service Widget with CSP without using unsafe-inline?

[Kevin Johnson]

I am trying to use the Service Management Widget (Contact Us button) on our websites but our content-security-policy (CSP) is blocking it. The only way to make this work is with setting the CSP with:

style-src 'self' 'unsafe-inline';

Is there another option to make this work? We will get flagged by security/pen tests if I were to set unsafe-inline.
