Thank you for your help in advance:)

You should be careful running commands with sudo if you do not need to. The problem is that you do not have an ssh key configured with github. To solve the problem, either add an ssh key to github or run these commands to clone using https instead of ssh:

$ git clone https://github.com/ethereum-optimism/optimism-integration.git
$ cd optimism-integration
$ sed -i -Ee's#[email protected]:([^/]*)/(.*).git#https://github.com/\1/\2.git#' .gitmodules
$ git submodule update --init --recursive
