Rstudio startup files in Linux

I run Rstudio in Linux (archlinux).
My setup to start from command line works as expected, with the following environment variables being set in one of my shell (zsh) startup files:

R_PROFILE_USER=/home/gabx/.config/r/.Rprofile
R_ENVIRON_USER=/home/gabx/.config/r/.Renviron

Now, starting Rstudio IDE, the app doesn't take into account my profile.

How can I tell Rstudio to read my Rprofile home file?
Thank you for help

no idea why, but RStudio is reading correctly my startup files now. Can't really say if I changed anything.
