Hi, how are u doing now?
I am one of the behind-the-scenes web developers. I have developed many web apps using Java Spring boot in the past period. I am also familiar with MuleSoft. If you are a developer, I can give you my code for review. Migration from mule3 to mule4 can be done smoothly. We'll add that feature to the sample project you've attached. I look forward to meeting you.
Best regards.
