News post does not appear on home page

For my part, the user had created a simple site page instead of a news post. I noticed this by checking the "Promoted State" column, which was set to 0 instead of 2, and the "First Published Date" column, which was empty. I then had to run my script, which converted the page into a news post and made it appear on the homepage.

Connect-PnPOnline -Url "xxxx" `
    -ClientId "xxxxx" `
    -Tenant "xxxxx" `
    -CertificatePath "xxxxx"

$page = Get-PnPListItem -List "SitePages" -Query "<View><Query><Where><Eq><FieldRef Name='FileLeafRef' /><Value Type='Text'>xxxxx.aspx</Value></Eq></Where></Query></View>"
Set-PnPListItem -List "SitePages" -Identity $page.Id -Values @{"PromotedState"=2}

$utcDate = (Get-Date).ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ssZ")
Set-PnPListItem -List "SitePages" -Identity $page.Id -Values @{"FirstPublishedDate" = $utcDate}
