Nano X

Running on MacOS Big Sur.
I have put Nano X in recovery mode:

ledgerctl info
Device: Ledger Nano X (0x33000004)
SE version: 1.2.4-5
MCU version: 2.10
Device is onboarded.
Device is running in RECOVERY mode.

I am trying to install a certificate:

ledgerctl install-ca "ledgerctl"

Installing custom certificates is not permitted on Nano X. Only apps delivered by Ledger can be installed on Nano X, unless you have a developer device.
