  Consider a log-correlated Gaussian field $\Gamma$ and its associated
imaginary multiplicative chaos $:e^{i \beta \Gamma}:$ where $\beta$ is a real
parameter. In [AJJ22], we showed that for any nonzero test function $f$, the
law of $\int f :e^{i \beta \Gamma}:$ possesses a smooth density with respect to
Lebesgue measure on $\mathbb{C}$. In this note, we show that this density is
strictly positive everywhere on $\mathbb{C}$. Our simple and direct strategy
could be useful for studying other functionals on Gaussian spaces.
