Statistical moments of $\frac X / ({X + Y)}$ when X$X$ and Y$Y$ are two independent random variables with a Beta distributionsdistribution

I'm trying to find the moments (or the pdf but I'm less confident there's a closed form) of $X /(X + Y)$$\frac X{X + Y}$ where X$X$ and Y$Y$ are two independent random variables with a Beta distributionsdistribution. There's a paper from Pham-Gia that I tried to read, and a similar (but yet different) question posted here, but they didn't help. I find the resulting distribution to be a lot similar to the Beta distribution.
