Tableau Map view Continent List

Question

I've been attempting to tidy up my data and create a column that represents the various continents, with the goal of eventually displaying them on a map.

However, it does not consider that column to be Geography, and even if I compel it to be, it does not shown on the map view. Do you have any recommendations?

Africa Europe and Asia North America is located in North America. Oceania (I also tried without it.) South America is a continent in South America.
