MSBuild, Can I take UsingTask output and use it in a Copy task?

Given: MSBuild that comes with Visual Studio 2019
I'm trying to take output from code task and use it in a CopyTask.

MSBuild Inline Task Reference Go

<Project ToolsVersion="15.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <!-- This simple inline task displays "Hello, world!" -->
  <UsingTask
    TaskName="HelloWorld"
    TaskFactory="CodeTaskFactory"
    AssemblyFile="$(MSBuildToolsPath)\Microsoft.Build.Tasks.Core.dll" >
    <ParameterGroup />
    <Task>
      <Reference Include="System.Xml"/>
      <Using Namespace="System"/>
      <Using Namespace="System.IO"/>
      <Code Type="Fragment" Language="cs">
<![CDATA[
// Display "Hello, world!"
Log.LogError("Hello, world!");
]]>
      </Code>
    </Task>
  </UsingTask>
</Project>

Somehow take code output and place it in a property so I can use it in a CopyTask?

  <Target Name="AfterBuild">
    <HelloWorld /> 
    <Copy SourceFiles="" DestinationFiles="<HelloWorld />"
  </Target>
