extFS for MacOS Ventura: cannot mount SD cards?

I just installed latest extFS for my Mac Studio Ultra (latest Ventura). Trial version.
After I restarted and gave all the permissions.

I'd like accessing in RO or RW (better) a microSD card formatted in Ext4 (Batocera Linux).
I can see the Linux partition but... cannot mount: the button is greyed.
The Verify option works and says everything ok.

Are there any probs in mounting SD cards?

Many thanks in advance, best

AUTO-SOLVED, in 20 minutes sorry :)
I only needed to detach and re-attach the SD card: it was probably mounted at startup by the OS, without extFS, and couldn't mount.
If you insert the card after... no problem at all.

Thanks the same :)
