Creating a NuGet package out of two projects, ends up with missing references

I have a MailService package that uses Azure queues. I have put the queue related logic in a separate project. I'm using this in my pipeline to create a package that has both projects:

  - task: NuGetCommand@2    displayName: "Pack MailService"    inputs:      command: 'pack'      packagesToPack: '**/Testing.MailService.csproj'      packDestination: '$(Build.ArtifactStagingDirectory)'      versioningScheme: 'off'      allowPackageConflicts: true      includeReferencedProjects: true

This is how the generated package looks like in dotPeek.As you can see the main package MailService references the queue one. The problem is that when I try using it in a different solution, I get the exception that Azure.Storage.Queues is not found. I do see that it exists in the references of the Storage.Queues project which is referenced by the first one. What exactly is the problem here?

These are my two project files

<Project Sdk="Microsoft.NET.Sdk"><PropertyGroup><TargetFramework>net7.0</TargetFramework><ImplicitUsings>enable</ImplicitUsings><Nullable>enable</Nullable><Version>1.0.0</Version></PropertyGroup><ItemGroup><PackageReference Include="Microsoft.EntityFrameworkCore" Version="7.0.3" /><PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="7.0.3"><PrivateAssets>all</PrivateAssets><IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets></PackageReference><PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="7.0.3" /><PackageReference Include="Microsoft.Extensions.Options.ConfigurationExtensions" Version="7.0.0" /><PackageReference Include="Microsoft.Extensions.Options.DataAnnotations" Version="7.0.0" /></ItemGroup><ItemGroup><ProjectReference Include="..\Testing.Storage.Queues\Testing.Storage.Queues.csproj" /></ItemGroup></Project>

<Project Sdk="Microsoft.NET.Sdk"><PropertyGroup><TargetFramework>net7.0</TargetFramework><ImplicitUsings>enable</ImplicitUsings><Nullable>enable</Nullable></PropertyGroup><ItemGroup><PackageReference Include="Azure.Storage.Queues" Version="12.13.0" /><PackageReference Include="Microsoft.Extensions.Options" Version="7.0.1" /><PackageReference Include="Testing.Utilities.OperationResult" Version="1.4.6" /></ItemGroup></Project>

I did try this workaround. However, that broke my Azure pipeline with:
