Setting up Pro Package with SSH key rather than an access to

Expected behavior I am trying to hide my access token (used to install mdb-react-ui-kit pro version) from showing up in github via package.json ... Thus, I am trying to set up with SSH so that the repo URL does not require an access token in my package.json ..

Actual behavior I generated a new ed_25519 key to $HOME/.ssh/private/ed_25519 but when verifying if I can connect, I get "failed to add the host to the list of known hosts".. See below the steps I took and the error I received..

ssh-keygen -t ed25519 -f $HOME/.ssh/private/ed_25519
( I did not add a passphrase )
cat ~/.ssh/id_ed25519.pub | clip
( I paste the clipped contents into a new SSH Key in Gitlab )
ssh-keyscan -H git.mdbootstrap.com
ssh -T git@git.mdbootstrap.com

Error Message on Git Bash

config.txt

# GitLab.com
Host gitlab.com
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/private/id_ed25519.pub

# Private GitLab instance
Host gitlab.company.com
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/private/id_ed25519.pub

** Desired Outcome ** I want to be able to have the following line in my package.json .. will this work with Github actions?

"mdb-react-ui-kit": "git@git.mdbootstrap.com:mdb/react/mdb5/prd/mdb5-react-ui-kit-pro-essential.git"
