Need to filter based on Logged in user in Desk Shorcut Filter

Hey,

I have a requirement that a field in a docType will save a user mail. I want to create a Desk Shortcut with a filter checking, the user email in the field is same as logged in session user.
Can anyone help me to sort this?

    "owner":frappe.session.user
