patience'MINIMUM' | 'LOW' | 'MEDIUM' | 'HIGH' | 'EXTREME' | 'MAXIMUM' | 'null' nullable

How long to wait for phone-number verification after a number is found: LOW waits up to 15 seconds, MEDIUM 30 seconds, HIGH 60 seconds, EXTREME 2 minutes, and MAXIMUM 10 minutes. Higher patience increases average response time but improves identity and reachability accuracy. MINIMUM is the least thorough verification option.
