For the convenience of debugging and testing functions related to sending SMS messages, I took the initiative to create a script and Slack application.

While working on the local project and on the test server, instead of real SMS sending, the messages are sent to a Slack channel along with the recipient's number.

It became much easier to test everything related to SMS, including logging in with a code from an SMS, notifications, etc.

Before developing this tool for debugging messages and logging in with a code, it was necessary to check the logs, which took a lot of time and was inconvenient.
