Get-PnPSiteTemplate' is not recognized as the name of a cmdlet

Hi,

I m trying to save a Communication site as a template ( XML) and then trying to resue it to apply to another site as described in the following.

https://learn.microsoft.com/en-us/sharepoint/dev/solution-guidance/introducing-the-pnp-provisioning-engine

But I m getting the following message when I run  Get-PnPSiteTemplate -Out "C:\test\PnP-Provisioning-FilePGS1.xml"
Get-PnPSiteTemplate : The term 'Get-PnPSiteTemplate' is not recognized as the name of a cmdlet, function, script file,
or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

FYI - I can connect to SharePoint site using PnP, but when I try to run Get-PnPSiteTemplate I m getting the error.

Can someone please help me fix this issue.

I have attached the modules available FYI.

Thanks.
