'Create Coalesce Column PowerBI DAX

I have below dataset as :

I want a new column as Country such that it picks non blank value available out of Country1, Country2 and Country3. Below is the expected output:

Country

Germany
Canada
India
Japan
US
UK

I tried the dax as:

Country = COALESCE(Coalese[Country1],Coalese[Country2],Coalese[Country3])

but it is not giving the intended result. How to use coalesce in DAX?
