Cant find shader/ppu cache on steam deck

Hi, i have a 64gb Steam Deck so I'm mindful of caches, where they are so i can delete or syslink them to a powerful sd card that can handle it without degrading performance. I installed the flatpack version of rpcs3 and emudeck confidured it but i cant find the caches for rpcs3. I've checked .var/app/net.rpcs3.RPCS3/cache but there is no folder for folklore, the only game i have like i have on my pc. i have a second rpcs3 folder, which inside has a cache folder with a bunch of unspecified ppu .sprx files. is that the whole cache?
I've checked
/.cache/ and no rpcs3 folder there

Can some one tell me where they are so i can keep them in check and use rpcs3 withotu fear of it eating my very limited emmc memory? thanks!
