Every week, once BAL destined for L2 gauges is minted and bridged, the notify_reward_amount(token) function in the L2 ChildChainStreamers must be called, which lets the contract know that it has received tokens and it should start distributing them.

Anyone can call that function if there's no active distribution period for that streamer. But otherwise only the AuthorizerAdaptor can call it.

In order to enable timely distribution of incentives, a multisig controlled by Balancer Labs is authorized to call that function through the AuthorizerAdaptor on Polygon and Arbitrum. This proposal seeks governance approval for the same to be possible on Optimism.
