What will be the exit condition for this async sequence loop?

I have the following code using async sequence

class Store {
    static let INSTANCE = Store()
    
    private var updateListenerTask: Task<Void, Error>? = nil
    
    private init() {
        //Start a transaction listener as close to app launch as possible so you don't miss any transactions.
        updateListenerTask = listenForTransactions()
    }

    private func listenForTransactions() -> Task<Void, Error> {
        return Task.detached {
            // STEP 1: Begin loop
            for await result in Transaction.updates {
                ...
                // STEP 2: Inside loop (No break/ return statement in this loop body)
            }
            // STEP 3: End loop
        }
    }

May I know, what will be the exit condition for this async sequence loop?

Or, it will always be an infinity loop? So far, per my testing, only STEP 1 and STEP 2 will be executed. STEP 3 is never executed.

Thank you.
