@triyam Thank you for your willingness! Unfortunately, I can't assign you the issue as it seems you have little experience in developing Capacitor plugins so far (your changes in definitions.ts does not work for Capacitor). Since I am currently the only maintainer in the Capawesome organization, I don't have the capacity to guide you through the bounty program and conduct intensive reviews. I really hope you understand that!
