How to filter Workflow Tasks in List view by current item

Hi,

I have a "main item" where there is a workflow running and some Workflow tasks being created.

I would like to show a List View control under the Main Item so that it shows only the Workflow Tasks filtered by the currnet item ID or Title/any column.

so far not succesfull. 

I tried to use "Related Content" column (WorkflowLink) and ID of the current, or Title of current item (since Related Content displays the actual title as a link) but no luck.

If I was able to use the DisplayForm in SharePoint list again I would just use Connected Webpart to show the filtered tasks on the same page,  but since Nintex Forms makes the DisplayForm not available anymore I am stuck and surely can reproduce the same in Nintex Forms ListView control.

any suggestion to achieve this would be great. 

thank you so much,

Francois.
