  You can now enable the AsyncioIntegration on demand, after calling sentry_sdk.init(). This is useful in scenarios where you don't have
  the event loop running early on, or when you need to instrument multiple event loops.

import sentry_sdk
from sentry_sdk.integrations.asyncio import enable_asyncio_integration

# Initializing the SDK as early as possible, when there is no event loop yet
sentry_sdk.init(
    ...
    # No AsyncioIntegration in explicitly provided `integrations`
)

async def main():
    enable_asyncio_integration()  # instruments the current event loop
    # ...your code...
