More account actions in Telegram

The Telegram bot became a fuller Nexus account area: actions that previously needed manual help are now available in one conversation.

New capabilities

• Create, rename, view, and revoke API keys.
• Review balance, top-ups, and API activity from dedicated screens.
• Open a support request and continue its conversation with its status and replies in the same chat.
• Recover a profile after moving to a different Telegram account.
• Find and attach a payment to the profile when the wrong Nexus ID was entered during payment.

Improvements and fixes

Navigation between balance, keys, and history is shorter, while ticket statuses and reply notifications are clearer. Profile and payment errors now lead to a safe recovery path instead of an unexplained rejection.

Compatibility and next steps

Existing keys and clients continue to work without changes. Start with the Nexus bot; the bot guide and help section describe the available flows.
