Display template overrides

Hello

I am trying to create an override for the search item display template for SharePoint. I have managed to make progress but do not know how to override ctx.RenderBody(ctx) within Item_Default_HoverPanel.html. This loads the search hover template body Item_CommonHoverPanel_Body.html.

I need to change Item_CommonHoverPanel_Body.html to customise the search hover template body so that it can show other metadata.

Thanks!
