Small Development Team: It’s also possible that ADBLogin is a small project maintained by a limited development team. In this case, they might not have open positions at the moment.
Here are some suggestions for further exploration:

Vietnamese Tech Forums: Revisit Vietnamese tech forums or communities where ADBLogin was mentioned. These communities might have discussions about the development team or if there are any contribution opportunities.
Contact Information: If you find any contact information for ADBLogin (perhaps from the code snippet), you could try reaching out to inquire about potential job openings or how to get involved.
While confirmed job listings are unlikely, these approaches might provide some insights into ADBLogin’s development structure and potential volunteer opportunities.
