Bear with me, this seems like it should be something simple, but the MQX Lite documentation isn't helping much with this. I have made two tasks in PE. Under the task settings, you can enable or disable the auto start. So let's say I want one task to run to initialize something, then let task 2 run. If I've made task 1 auto start and task 2 isn't, how do I start task 2? What is the difference between a task descriptor and task ID? All the examples I see use _create_task_at() to return the task ID. I can't even find the word "descriptor" in the MQX Lite user's guide. I think I want to use _task_ready() to start it, but it seems like there's no direct way of getting the descriptor for it.
