Option to display only issues linked via the Agile Docs Parent on Hierarchy Tree View#14

Currently, the issues that are displayed on the Hierarchy Tree View are a combination of issues linked via the Agile Docs Parent link type and native Jira linkage (e.g. issues that are linked to an Epic would have Epic Link value and would appear under the Issues in this epic section of that Epic).

As a user
I need to have the option to filter out the default linkage i.e. issues linked natively
So that I can display only issues that are linked via Agile Docs Parent link on the Hierarchy Tree View.
