Hey @HungNgien - I've reviewed your changes - here's some feedback:

Overall Comments:

• Please remove the GitHub token placeholder from pyproject.toml to avoid potential security issues. Token handling should be done entirely through environment variables or configuration.
• The PR would benefit from more detailed documentation explaining the rationale for replacing the built-in PayPal plugin with the private repository version, along with any necessary migration steps for existing users.

Here's what I looked at during the review

• 🟢 General issues: all looks good
• 🟢 Security: all looks good
