Stuck migrating to new style console extension (Configuration Manager 2103).

having tried to add our custom node in Assets and Compliance.

Here is the node xml (its minimalistic version which reproduces the problem):

<?xml version="1.0" encoding="utf-8"?>
<!-- SCCM Console / Assets and Compliance / Parallels Device Management -->
<RootNodeDescription Id="ParallelsManagementAdd-on" SearchFolderId="ParallelsManagementAdd-on" DisplayName="Parallels Device Management" Description="Manage Mac computers and Parallels Desktop.">
  <ViewAssemblyDescriptions>
    <ViewAssemblyDescription>
      <Assembly>AdminUI.HomePageView.dll</Assembly>
      <Type>Microsoft.ConfigurationManagement.AdminConsole.HomePageView.ViewDescription</Type>
      <CustomData>
        <HomePageConfigurationData xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
          <TileList>
            <TileDescription ShowGenericGettingStartedTile="true" />
          </TileList>
        </HomePageConfigurationData>
      </CustomData>
    </ViewAssemblyDescription>
  </ViewAssemblyDescriptions>
</RootNodeDescription>

As a result: the node itself did appeared (on the left side of console window), but the expected node view (on the right side) is not shown.

Also we have the following entry in SmsAdminUI.log:

[11, PID:9572][07/22/2021 16:19:19] :The 'AssemblyPath' assembly (C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\Extensions\91269007-78e9-4cc6-85dc-a5305acb4d39\10.0\bin\AdminUI.HomePageView.dll) was not found.\r\nSystem.IO.FileNotFoundException\r\nCould not load file or assembly 'file:///C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\Extensions\91269007-78e9-4cc6-85dc-a5305acb4d39\10.0\bin\AdminUI.HomePageView.dll' or one of its dependencies.

   at Microsoft.ConfigurationManagement.AdminConsole.Common.UtilityClass.LoadAssemblyByName(String assemblyName, Boolean reflectOnly)\r\n

So, the question is What are we doing wrong?

Thanks.
