[Tex/LaTex] Why can’t I put a comma in a \newtcolorbox

Question

When I try to put a "," in the mybox environment, I get the error:

! Package pgfkeys Error: I do not know the key '/tcb/FM and PM and Narrowband F
M' and I am going to ignore it. Perhaps you misspelled it.

Is there a way to put a comma "," in the tcolorbox header so that my header appears as: Angle, FM, and PM and Narrowband FM?

Answer 1

Just put the title with the comma into two more { }, otherwise, I think tcolorbox thinks there is another parameter.
