in iOS where are no Activity. Is's analogue calls UIViewController.
For Android you can read Android docs. You need to use Lifecycle callbacks. https://developer.android.com/guide/components/activities/activity-lifecycle

For iOS you can use this approach:

ComposeUIViewController(
    configure = {
        delegate = object: ComposeUIViewControllerDelegate {
            override fun viewDidLoad() {
                // Some reaction
            }
            override fun viewWillAppear(animated: Boolean) {
                // Some reaction
            }
            override fun viewDidAppear(animated: Boolean) {
                // Some reaction
            }
            override fun viewWillDisappear(animated: Boolean) {
                // Some reaction
            }
            override fun viewDidDisappear(animated: Boolean) {
                // Some reaction
            }
        }
    }
) {
    Text("Here your Compose code")
}
