And if I want to use this application for sms OTP verification.
so I will reduce interval to seconds from minutes.
So for example if I set interval 5 seconds and 100 messages in this period. what are the limitations.
what is the maximum number of messages in minimum time period?
Can you talk about limitations?

For example;
I am seeing,
SendTask.kt line:81: Thread.sleep(500)

Can we reduce this to 100 ms?
