I'm using the latex2exp package to create some equations that will be placed on plots or on the axes. Despite using the bold = TRUE option within the arguments of the TeX() function, the Greek letters and brackets do not appear in bold. Would anyone know how I can get this formatting?

Additional help: It appears that math operators like + and = are also not rendered in bold when I try to put space between terms in the equation.

library(latex2exp)

Equation1 <- TeX(r"($\left(\frac{\mu}{\beta^2}\right) + constant$)",
                bold = TRUE)

Equation2 <- TeX(r"($\left(\frac{\mu}{\beta^2}\right)+constant$)",
                 bold = TRUE)

plot(Equation1)
plot(Equation2)
