TRIM in Qubes OS


I have a SSD and followed the disk-trim documentation. Everything seems work fine. I just have a question about TRIM in Qubes OS. If i followed the documents. does it mean that if i delete something in any qube (AppVM, Template, etc) the TRIM service will handle it? Or i should make make the trim service in the qubes itself? In other words: if i’d like to run a manual TRIM command with fstrim -av is it enough to run in dom0, or i need to run it in the AppVM itself?

Thanks any help!
