How to see emails shared from Redwood Outlook plugin in SUI?

Summary:

Customer has the latest Redwood Outlook add-in installed, but they're using SUI. Customer shared email from Outlook to opportunity, and the e-mail is not visible in any tab of the opportunity.

However, it is visible in the redwood layout of the opportunity, but customer has not moved to redwood. We need to see the email in SUI.

According to some community posts and documentation, the new add-in should also work with SUI.

In addition, when the customer tried to open a record from the Outlook add-in, it redirected the user to the Redwood layout, instead of the SUI layout.
