Hi Lym_Wale 

To add elements to the default "Related Items" column in a default SharePoint task list you need to uses the following REST endpoint

_api/SP.RelatedItemManager.AddSingleLinkToUrl


You can use it like this in PowerAutomate



POST _api/SP.RelatedItemManager.AddSingleLinkToUrl
Content-Type application/json;odata=verbose

{
    "SourceListName":"Tasks",
     "SourceItemID":1,
     "TargetItemUrl":"/sites/classic/Shared Documents/Document.pdf",
     "TryAddReverseLink":true
}




This call adds the file "/sites/classic/Shared Documents/Document.pdf" to the task with the ID 1 in the task list "Tasks" as a related item.

Best Regards,
Sven
