Error: Class "GitLab\Client" not found in Drupal\config_pr_gitlab

The Config Pull Request GitLab Support module has different dependencies
See instructions in https://git.drupalcode.org/project/config_pr/-/tree/8.x-1.x/modules/conf...

Dependencies
- m4tthumphrey/php-gitlab-api:^11

Installation
- Use composer to make sure you will have all dependencies: composer require m4tthumphrey/php-gitlab-api:^11

Please let me know if that works.

Thanks!

One thing I see is that we have our own private gitlab instance on our own url, so this wouldn't work, I don't think with a custom url like https://gitlab.ourdomain.com as the field input help text assumes we're only entering a user name and repo name:

Repo user name
Example: In https://github.com/marcelovani/captcha_keypad the repo user name is `marcelovani`

Repo name
Example: In https://github.com/marcelovani/captcha_keypad the repo name is `captcha_keypad`

@stewest I think to use self hosted Gitlab, it could be done by extending the Gitlab class, like it was done here https://git.drupalcode.org/project/config_pr/-/blob/8.x-1.x/src/RepoCont...
