Task Preview / Add-ins for Microsoft Outlook

Hi Everyone,

I am having the following scenario, we need to send an email user , In the email body we should show the form with approve and reject option for a request.

Business requirement: we should not create Appian account for the user, and they should be completing the task from outlook email body itself, without logging into Appian.

I have tried the steps mentioned in Task Viewer Add-in for Microsoft Outlook - Appian 22.2 but I when I click on the task link , user is navigated to Appian Environment.

FYI: I can see task viewer add-in was added to my account.
