#### Context:
Our first iteration was to add our billing page but after a few iterations, we decided to postpone it in favor of more important features.

#### This Change:
1. creates a link for a private user session
2. redirect the user to that page (open in a new tab) when the user clicks on the billing tab

#### Test Plan:
Go over how you plan to test it. Your test plan should be more thorough the riskier the change is. For major changes, I like to describe how I E2E tested it and will monitor the rollout.
