Engineering & Technology

Software engineering is not mentioned in the list. Since the Telegram entity is likely related to maps, I'll choose the category, Self-Interactive maps aren't listed explicitly but this item is close, so Maps would be under "Gaming & Esports" or "Other / Unclassified".

Applying object- a cyber communication app user can be classified under a platform category title but best categorization turns ou for this could be Engineering

Engineering port not available

IT teaches software engineering through practice, and has studies cases of decompiling, so I would categorize Telegram as "Technology & Programming".

Information technology, software engineering, or simply 'Technology'
