Sign internal assemblies of a nuget package with Microsoft's Trusted Signing

Presently hosting NuGet artifacts internally using Azure DevOps, but need to sign the contents (signing the NuGet Package itself is not required). Currently the following pipeline task is used to generate the NuGet package:

- task: DotNetCoreCLI@2  displayName: 'Build Nuget Package'  inputs:    command: 'build'    projects: '$(solution)'    arguments: '-c $(buildConfiguration)'

But this automatically generates the *.nupkg file, inside are several assemblies for various runtimes that need to be signed. How can Microsoft's Trusted Signing be used to do this?
