Thanks for your feedback, the feature is currently in preview. Documentation can be viewed here: https://docs.microsoft.com/en-us/office/dev/add-ins/reference/manifest/supportssharedfolders
We are actively working on making it generally available and will update the status as soon as it is done.Karin commented
Hi, is there any update on when this will be available in targeted release/general availability? Also, is joining the Office insider program a requirement for testing this feature? the documentation only says "may have to join".
