How to prevent coupling between our code and third party libraries?

Imagine we want to use the following library like this:

use GrahamCampbell\GitHub\GitHubManager;

class Foo
{
    private GitHubManager $github;

    public function __construct(GitHubManager $github)
    {
        $this->github = $github;
    }

    public function bar(): array
    {
        $this->github->issues()->show('GrahamCampbell', 'Laravel-GitHub', 2);
    }
}

Does it makes sense to create an interface like:

interface GitHubManagerInterface
{
    public function showIssues(): array;
}

Then implement it and bind the implementation to the interface and use it in my code like the following?

class Foo
{
    private GitHubManagerInterface $github;

    public function __construct(GitHubManagerInterface $github)
    {
        $this->github = $github;
    }

    public function bar(): array
    {
        $this->github->showIssues('GrahamCampbell', 'Laravel-GitHub', 2);
    }
}

Or there is a better way to prevent coupling? Or it's over engineering? :)
