# Usage example:
post_data = {
    'link': 'https://example.com',
    'sender': 'Sender Name',
    'text': 'This is the main text of the post.',
    'extra': 'Additional information (optional)',
    'image': []
}

# To call an async function, you need an event loop, like this:
import asyncio
loop = asyncio.get_event_loop()
loop.run_until_complete(sendMsg(post_data['text']))
