What is the purpose of the mandatory subscription module in a Telegram bot?

The mandatory subscription module to a chat or channel for a bot is a special tool that allows you to automate the process of attracting and retaining subscribers to your channel or chat.

The main goal of this module is to increase the number of subscribers and activity in your channel or chat. How does it work? When a user starts interacting with your bot (for example, sends it a message or performs a specific command), the bot checks whether this user is subscribed to your channel or is in your chat. If not, the bot sends the user a message offering them to subscribe to your channel or join your chat.

This can be very useful for marketing purposes. For example, you can use this module to attract more people to your content, promote your products or services, increase your audience, etc.
