Pre-install SSH keys on vps reinstallation

Hello guys,

I was trying to automate my workflow to setup a VPS using Infrastructure as Code (IaS) software, and I was trying to add ssh key into server as smooth as possible.

On my VPS dashboard, on reinstallation I saw the option to pre-install ssh key, and to do so I have to "add a key in my Account section", see below :



So, trying to add this key on my account section, I didn't find anywhere to add my key. I was wondering if I was in a wrong "my account section", if something else exist elsewhere, and I found this tutorial where they perform this task, using a previous ovh interface.
It have a "My ssh keys settings", which isn't available in the actual interface.

So, am I looking in the wrong place ? Does the ssh settings' location change ? Or is this feature deprecated by ovh, the ssh key list removed but still having this option visible for the VPS reinstallation ?

Thx for your response.
