how to make simple telegram user bot?

what is telegram userbot

A Telegram clientbot is a form of robot account that individual consumers utilize rather than clusters or channels. In contrast to standard robots, which are constructed to engage with multiple consumers simultaneously, clientbots prioritize supplying personalized automation and customization choices for individual consumers. Telegram clientbots are erected employing Telegram's Bot API, which grants creators the ability to develop bespoke bots that can dispatch and accept messages, interact with Telegram's API, and accomplish an extensive variety of other duties. Clientbots can automate assignments such as relaying messages, regulating your connections, transmitting reminders, and even participating in games. It is noteworthy that using clientbots is not officially supported by Telegram, and in particular circumstances, could contravene the platform's terms of service. Consequently, it is vital to use clientbots responsibly and within the boundaries of what is sanctioned by Telegram.
