External users invitation : how to display the date on which the invitee has accepted the invitation

Hello All,

We are using SharePoint Online to share information with multiple partners defined as external users. We want to know when the invitee accepted the invitation.

Under "Users and Permissions", "Access requests and invitations", "Show history", the "Date" column is the date the invitation was sent, not the date the guest accepted the invitation.

Is it possible to modify the History list to add this date? Is it possible to extract this information with a powershell script?

Thanks for answering.

Stephane
