Joining the same channels and groups will help you know where the person is interacting. If the person whom you want to check is online on Telegram and is part of the same channel or group as you, you need not have to do much.
You just have to wait for the person to interact with other participants there, and the app will immediately notify you whenever they message or post anything on those channels or the groups.

The moment you receive the notification indicating that person’s name, know that they are online on Telegram.
In a Telegram channel or group, you can easily view the online members. For that just select the group that is common to both of you and then open the chat window of that group.
