asyncio, how do I keep 3 servers running

[davefes]

I found this example:
https://groups.google.com/g/python-tulip/c/yg79L1niUsc
but I think a few things have changed in the last 9 years.

However, I am struggling to place async with server: in the correctly. The following will start one server then seems to wait for ??

def main():
    for i in range(3):
        print("Starting server {0}".format(i+1))

        server = await asyncio.start_server(handle_msg, config.server, 8089+i)

        async with server:
          # wait a moment
#            await asyncio.sleep(10)
            while True:
                await asyncio.sleep(1)  # can be 1 second


asyncio.run(main())

How do I keep all three servers running?

Found this:
# serve forever
async with server1, server2:
while True:
await asyncio.sleep(3600)
