What is the white tribe in Panama?

Excuse me, but could you please elaborate on the term "white tribe" in the context of Panama? I'm curious to know if this is a specific cultural, ethnic, or social group within the country, and if so, what are its defining characteristics? Additionally, is this term widely recognized and accepted within Panama, or is it more of a niche or controversial term? I'm seeking clarity on this matter as it's not a term I'm familiar with in relation to Panama.
