Empty sharepoint online folder - powershell

Question

I am looking for a way to automatically empty a folder in sharepoint online once a day. I think the best way to do this is using a powershell script from a local server. I tried to search this on google but then I can only find how to delete a folder. But I want to delete all the content within a folder and not the folder itself. Does anyone know a good solution or powershell script for this?

Oke i got a working powershell script from the URL that Theo provided: [https://www.sharepointdiary.com/2018/05/sharepoint-online-delete-all-files-in-document-library-using-powershell.html][1]
the script looks like this:
#Load SharePoint CSOM Assemblies
#Download Sharepoint CSOM Assemblies from https://www.microsoft.com/en-us/download/details.aspx?id=42038
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
#Variables for Processing
$SiteURL = "https://tenantname.sharepoint.com/sites/TestTeam"
$LibraryRelativeURL = "/sites/TestTeam/Shared Documents/TEST/TestFolder"
Try {
#Get Credentials to connect
$Cred = Get-Credential
$Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)
#Setup the context
$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$Ctx.Credentials = $Credentials
#Get the Library and Files
$Folder=$Ctx.Web.GetFolderByServerRelativeUrl($LibraryRelativeURL)
$Ctx.Load($Folder)
$Files = $Folder.Files
$Ctx.Load($Files)
$Ctx.ExecuteQuery()
#Iterate through each File in the Root folder
Foreach($File in $Files)
{
#Delete the file
$Folder.Files.GetByUrl($File.ServerRelativeUrl).Recycle() | Out-Null
Write-host -f Green "Deleted File '$($File.Name)' from '$($File.ServerRelativeURL)'"
}
$Ctx.ExecuteQuery()
#Process all Sub Folders
$SubFolders = $Folder.Folders
$Ctx.Load($SubFolders)
$Ctx.ExecuteQuery()
Foreach($SubFolder in $SubFolders)
{
#Exclude "Forms" and Hidden folders
If( ($SubFolder.Name -ne "Forms") -and (-Not($SubFolder.Name.StartsWith("_"))))
{
#Delete the folder
$Folder.Folders.GetByUrl($SubFolder.ServerRelativeUrl).Recycle()| Out-Null
Write-host -f Green "Deleted Folder '$($SubFolder.Name)' from '$($SubFolder.ServerRelativeUrl)'"
}
$Ctx.ExecuteQuery()
}
}
Catch {
write-host -f Red "Error:" $_.Exception.Message
}
