Get-PnPSiteTemplate with all client side pages that promoted as templates

[mohammadamer]

I'm working on a challenge to copy page templates across sites.

I see there is a parameter [-IncludeAllClientSidePages] with Get-PnPSiteTemplate
If there is a parameter to get all client side pages that are promoted as page templates, That would be awesome and will save time to loop through all client side page and get the page templates only. Hopefully that this would be possible.
