I've tried to find a WMS service which shows:

• countries boundaries (it works like shapefile from https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/110m/cultural/ne_110m_admin_0_countries.zip)
• countries names (e.g. Germany, Poland, France,...)

But it should not contain any background colors in the countries, so it is transparent for everything, except the countries' borders and names.

If someone knows about a service which provides this WMS layer freely, please let me know. Thanks.
