SignTools.exe Where is it??

I am trying to build a docker container with a trimmed down msbuild tools in it.
I am currently using an offline installer that I created with this command:

.\msbuild2019.exe --layout C:\dev\jenkins-slave-msbuild\OfflineVS2019 --add Microsoft.VisualStudio.Workload.MSBuildTools --add Microsoft.VisualStudio.Component.VC.ATL --add Microsoft.VisualStudio.Component.VC.Tools.x86.x64 --add Microsoft.VisualStudio.Component.Windows10SDK.17763 --add Microsoft.VisualStudio.Component.Windows10SDK --add Microsoft.Component.ClickOnce.MSBuild --lang en-US

It builds okay but the container doesn't have SignTool.exe in it.

Is there a component that I should add? and if so can you reference the component on this page? Just saying it gets installed with Visual Studio installation is pretty useless because there are a milion optional components in a visual studio installation.
