Customizing the visual backdrop during video calls for privacy or presentation
Hi, EUC_Nate,
I'm happy to help you today.
To clarify, are you referring to the new Teams which has the logo shown below? If so, I'm afraid yes, the custom backgrounds are not visible from the background effects options.
It may be one of the features that are being worked on at the moment for this new version of Teams.
Let me know if this answers your question.
Kind regards,
