Step 1: Click the Bot Link and Open Telegram
Click the bot link below (you can also choose based on your project's needs) and open your Telegram.
Step 2: Click 'Add to Group' and Select the Desired Group
Simply click 'Add to Group' and then choose the group you'd like the bot to be added to.
For a smoother process, suggest doing this step on your mobile, as the 'add to channel' option may not appear on your computer.
Step 3: On the Pop-up Page, Click 'Add Bot as Admin'
Grant the bot with all default admin permissions and click 'Add Bot as Admin'. On the subsequent pop-up, click 'Add as Admin' again.
Step 4: Confirm the Bot permission
Head back to your Telegram group and verify under the Admin list whether the bot has been successfully added.
