Is there some way of getting bold Greek letters.

[MikelisBickis]

Canvas has a convenient way of inputting math formulas using LaTeX code.   Many of the features work well, but it seems not possible to enter Greek letters or math symbols in boldface.   There are LaTeX packages that allow \mathbf to work on Greek letters, as well as other packages for using \bm or \symbf but these seem not to be implemented in Canvas.   Is there another way of entering a bold face Greek letter?

This seems to work: Writing direct latex \boldsymbol\alpha gives a bolded alpha but to make a math style x bold I had to use \boldsymbol{x}
