Change Display Name of Azure-Bot via API

Case may depend, below the possible alternatives:

1. Create Multiple Bots with Different Display Names
•    Register separate Azure Bot resources with distinct display names.
•    Use conditional logic in your Power Automate Flow to select which bot initiates the call based on context.
2. Customize the Call Notification Message
•    While you can't change the bot name, you can customize the message content shown in the Teams notification: 
o    Use the subject or callbackContext fields in the Graph API call payload.
3. Use Azure Communication Services (ACS) for More Flexibility
•    ACS allows custom user identities and display names for participants.
•    You can simulate bot behavior using ACS and assign a dynamic display name per session.
•    This requires more setup but gives you full control over identity presentation.
