ObservableInput<T> should support Thennable<T>, not PromiseLike<T> about rxjs HOT 1 OPEN

// Define the Thennable interface
interface Thennable {
then(onresolved?: ((value: T) => void) | null | undefined, onrejected?: ((reason: any) => void) | null | undefined): void;
}

// Function that takes an ObservableInput
function processObservable(observable: Thennable) {
// Simulate processing the observable
observable.then(
(value) => {
console.log("Resolved:", value);
},
(reason) => {
console.error("Rejected:", reason);
}
);
}

// Example usage
const myObservable: Thennable = {
then: (onresolved, onrejected) => {
// Simulate resolving the observable after a delay
setTimeout(() => {
if (Math.random() < 0.5) {
onresolved?.("Success");
} else {
onrejected?.("Failure");
}
}, 1000);
},
};

// Process the observable
processObservable(myObservable);
