How do I make Plug-in for DxO Pure Raw become available as 'Edit in.. from within Lightroom Classic?

RIght now, I can right-click (option click on my Mac) on an image in Lightroom and it gives me menu choices of all that I have installed for Topaz Plug-ins. I would like to add the abilty to use DxO Pure Raw as a choice in this menu "Edit in.... " in the drop down menu. Is this possible to add and work with from within Lightroom or am I barking up the wrong tree? - I have installed DxO Pure Raw, re-started my computer and it is linked to Lightroom, somehow, but does not show up in the "Edit in..." menu. This an area outside of my specialty  so need help.

TIA,  Ken
