"At Least version X" Nuget Dependency Declaration?

This document is a bit confusing. How can I specify that I depend on AT LEAST version 1.2.0 of package XPTO? is it <PackageReference Include="XPTO" Version="1.2" />?

My intention is that if a version 1.2.1 or 1.3 or 2.0 comes along, it will restore the newest available, and not fixed to 1.2.

When I use the Version="1.2" notation visual studio keeps warning me that an update is available.
