To include a link of the SharePoint list item in an email, you can configure it as follows:
In the email body, use the sample expression below to create a link to the list item. This sample expression creates a link to the list item with the text "Open List."
<a href=[[@Web.Url]]/Lists/Obi%20Test%20List/EditForm.aspx?ID=[[ID]]>Open List</a>
You can replace the Obi%20Test%20List with your list name as it appears in your form's URL. The list in this example is called Obi Test List. The "Open List" link should open the Edit form of the item.
