Importing an SSH Key

I have been trying to follow a guide for creating and importing an SSH Key:
https://docs.ovh.com/ca/en/public-cloud/create-ssh-keys/

The key has been created but I am unable to advance to the import step.
I have uploaded a screenshot.
It's also online: https://i.postimg.cc/cJPtMGZN/image.png

Supposedly I have to click on Public Cloud, and then I would see on the left-hand menu the INFRASTRUCTURE menu.

After clicking on Public Cloud, what I got was a prompt for a payment mean, and eventually ended up paying 10€ + VAT for credits, which I have no idea what they are used for.

Most importantly, even after buying these credits, I still cannot see the INFRASTRUCTURE menu, and therefore cannot go any further. Bottom line: what the guide shows is not the same that I can see. Hence, I cannot go any further.

Thanks in advance for any help.
