async def asend_text():
    response = await client.send_text(
        recipient_id="USER_PSID", message_text="Hello from Python!"
    )
    print(response)

🖼️ Sending an Attachment By URL

async def asend_remote_attachment():
    response = await client.send_remote_attachment(
        recipient_id="USER_PSID",
        image_url="https://example.com/image.jpg",
    )
    print(response)

    except MessengerAPIError as e:
        print(f"GAPI Error: {e}")
