You can follow instructions in this video to update your script running unattended exchange online scripts.

High Level these are the steps :

# create a self signed certificate
New-SelfSignedCertificate -FriendlyName "Exch Unattended Script" -Subject "Exch Unattended Script" -CertStoreLocation "cert:\CurrentUser\My" -KeySpec KeyExchange

# Export Certificate
$cert = Get-ChildItem -Path Cert:\CurrentUser\My\{put certificate thumbprint}

# Create App Registration and grant admin consent
Grant Exchange.ManageAsApp Right under Office 365 Exchange Online

# Assign Exchange Admin Role to the newly registered App.

# Upload Certificate Public Key to recently created App in Azure.

# Run Command On Prem to find if unattended script works

# Sample Script for task scheduler job to export script.
