Find all files on SharePoint Online between two date

LeonPavesic I had to uninstall and reinstall the sharepoint module. Even after that I got this message:

$files = Get-SPOSite $sourceSiteUrl | Get-SPOWeb | Get-SPOList $sourceLibraryName | Get-SPOListItem | Where-Object {
($_.FileSystemObjectType -eq "File") -and ($_.FieldValues.Created -ge $startDate) -and ($_.FieldValues.Created -le $endDate)
}
Get-SPOWeb : The term 'Get-SPOWeb' 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.
