Could not clone foundry-zksync in locally

[nathaniel1616]

Hi, I am using WSL2 ubuntu on windows 11
I tried to clone it locally in my ubuntu terminal with this command

$ git clone git@github.com:matter-labs/foundry-zksync.git

This is the output , I got from the terminal

Cloning into 'foundry-zksync'...
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

I figure it must have something to do with this line git@github.com: Permission denied (publickey).
How do I solve this problem? Thanks

I have been able to clone the repo with

$  git clone https://github.com/matter-labs/foundry-zksync.git

Yet I would like to know more about cloning using this format git clone git@github.com:matter-labs/foundry-zksync.git
