How to add "Lookup in Dictionary" to context menu of Mojave?

I'm running Mojave 10.14.6 on a MacMini 2018.

How to customize the Mojave context menu to be able
to hi-light a word, in any app, right-click it and in the
context menu an option to "Lookup in Dictionary" appears?

Selecting that context menu option would then open
Dictionary, lookup the selected word and display the result.
