Release management on Azure devops dashboard

Hello, Everyone!

I've been struggling to promote the feature's release. We have three product teams, and I am responsible for releasing features to approximately 16 countries. As a result, the key account managers and relationship managers of the various regions will always ping me to inquire about the release dates of their region and regions to be released on that date.

Since I have ADO, how can I establish boards for each region to show them the future and release date? It should, for example, display them the progress and inform them that it will be launched on this exact date.

Can you tell me how I can increase visibility using the ADO board to highlight release management?

Thanks,
