@Alba4 I saw that you’ve been in touch with someone on the support team regarding this already, but just wanted to follow up to say on this post that this is not possible (and I don’t have any indication on if/when this would become a feature in the future on my end).
I’m going to convert your topic to a ‘share feedback’ one so others looking for this capability will be able to upvote. If you have any additional questions, feel free to start a new topic.
Our organisation would also highly appreciate this. We’ve recently switched to SCIM user provisioning for Figma access management within our Figma Organisation. But we keep getting Figma/FigJam upgrade requests from our users. We’d like to be able to put up a banner to tell users that Figma/FigJam access is now managed via our internal identity provider. Banners will also come in handy for notifying users of similar future changes and as we enable new functionality within our Figma org. i.e. Figma AI.
