I see, so you want to consistently refresh the token? Unfortunately this is not supported, per the github issue here : https://github.com/MicrosoftDocs/office-docs-powershell/issues/3351
If you're interested in this feature, I suggest submitting an issue against here : https://github.com/MicrosoftDocs/office-docs-powershell/issues/new
And if there's enough community support the product team will look into implementing this feature accordingly. Thanks for your feedback!
