Regularly triggers checks every hour using a schedule.\n4. Executes the scheduled process and checks the status of tasks.\n5. Allows manual testing of CapSolver through a manual trigger.\n\n### Setup steps\n\n- [ ] Set up webhook credentials for 'Receive Solver Request'.\n- [ ] Configure CapSolver with necessary keys for all CapSolver nodes.\n- [ ] Assign necessary permissions for HTTP request to reCAPTCHA endpoint.\n- [ ] Review and adjust the schedule in 'Schedule Trigger'.\n- [ ] Test manual execution with 'Manual Trigger'.\n"
