Batch Approve Express ECOs

We are using Innovator 24 in a large course (550+) students. This Fall we will be having all students submit their work using the Express ECOs. Once items are scored, we would like to be able to Batch Approve the ECOs by selecting the desired ECOs with an Action available in the contextual menu to approve the selected ECOs.

Any assistance with writing the method that would enable this would be greatly appreciated.
