Do you think there is a way to get a nice form of the expression below
$$\Im{\left( \text{Li}_2\left(\frac{3}{5}+\frac{4 i}{5}\right)- \text{Li}_2\left(-\frac{3}{5}+\frac{4 i}{5}\right)+ \text{Li}_2\left(-\frac{4}{5}-\frac{3 i}{5}\right)- \text{Li}_2\left(-\frac{4}{5}+\frac{3 i}{5}\right)\right)}$$
and if possible to get rid of dilogarithm entirely? Some hints, clues, suggestions?
