Retrieving Templates Used on Subsites

[YTtatata]

I would appreciate the assistance of anyone knowledgeable about this matter.
I am currently participating in an SPO to SPO migration project,
I am using PnP.Powershell to investigate the status of the site collection from which we are migrating.

I am using the following command in PnP.Powershell to get the results,
I am having trouble getting the same results for the modern and classic team sites.

$siteUrl = "https://test.sharepoint.com/sites/siteCollectionName"
$con = Connect-PnPOnline $siteUrl -Interactive
$subSitesInfo = Get-PnPSubWeb -Recurse -Includes WebTemplate -Connection $con
$subSiteInfo.WebTemplate

Results→STS

It would be most desirable to be able to obtain values such as "STS#3" or "STS#0" as in the case of the following command,
However, we would like to know if there is any other way to determine the value.

Sample:

$siteUrl = "https://test.sharepoint.com/sites/siteCollectionName"
$con = Connect-PnPOnline $Data.url -Interactive
$siteCollectionInfo = Get-PnPTenantSite -Identity $siteUrl -Connection $con
$siteCollectionInfo.Template
