@MarvisKisakye1 Did you get any solution of this? I am also looking for same solution
I have tried many ways in config.daml but no success, below are sample entries in file i tried.
<!-- 1. esri_editing_Attributes_RelatedNonFeatureRowContextMenu: Drill down from the spatial feature to the Non Spatial object for the Context Menu Item to appear
e.g. Right-clicking a Related record (child record) in the top selection tree. -->
<updateMenu refID="esri_editing_Attributes_RelatedNonFeatureRowContextMenu">
<insertButton refID="POC_Addins_CustomContext_Views_CatalogHelpBtn" separator="true" placeWith="esri_editing_Attributes_StandaloneTablePropertiesContextMenuItem" />
</updateMenu>
<!-- 2. esri_editing_Attributes_NonFeatureRowContextMenu: is used for standalone table records that are open in the Attributes Pane but are not currently being viewed as a "related child" of a map feature.
e.g. In ArcGIS Pro, when you open a standalone table (one without geometry) and select a row, that row appears in the Attributes Pane. This specific refID controls the right-click menu for that record's entry in the selection tree.-->
<updateMenu refID="esri_editing_Attributes_NonFeatureRowContextMenu">
<insertButton refID="POC_Addins_CustomContext_Views_CatalogHelpBtn" separator="true" placeWith="esri_editing_Attributes_StandaloneTablePropertiesContextMenuItem" />
</updateMenu>
<updateMenu refID="esri_editing_Attributes_FeatureContextMenu">
<insertButton refID="POC_Addins_CustomContext_Views_CatalogHelpBtn" separator="true" placeWith="esri_editing_Attributes_LayerPropertiesContextMenuItem" />
</updateMenu>
<!-- esri_editing_Attributes_FeatureRowContextMenu: Right-clicking a Map Feature (Point, Line, Poly) in the top selection tree. -->
<updateMenu refID="esri_editing_Attributes_FeatureRowContextMenu">
<insertButton refID="POC_Addins_CustomContext_Views_CatalogHelpBtn" separator="true" />
</updateMenu>
<!-- esri_editing_AttributesPaneAttributesContextMenu: Right-clicking the actual field values/cells in the bottom grid. -->
<updateMenu refID="esri_editing_AttributesPaneAttributesContextMenu">
<insertButton refID="POC_Addins_CustomContext_Views_CatalogHelpBtn" separator="true" />
</updateMenu>
<updateMenu refID="esri_editing_AttributesPane_GridContextMenu">
<insertButton refID="POC_Addins_CustomContext_Views_CatalogHelpBtn" separator="true" />
</updateMenu>
