The term 'Test-AzTemplate' is not recognized as a name of a cmdlet

I downloaded the last release, unzipped it to a folder

In PS, Update execution policy to unrestricted for my user useeion, then I isssued

` Import-Module C:\Projects\AzureDevOpsProjects\ARM\arm-ttk\arm-ttk\arm-ttk.psd1`
without any error but running
`Test-AzTemplate -TemplatePath .`
gives always the following error

> Test-AzTemplate: The term 'Test-AzTemplate' is not recognized as a name of a cmdlet, function, script file, or executable program.
> Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Am I missing something? Thanks for your help

Start with the downloaded release and the arm-ttk.psd1 module entry point, reproducing the import and Test-AzTemplate commands in PowerShell. Check whether importing the module exposes Test-AzTemplate as a callable command; done means the documented release setup makes that command available without the reported recognition error.
