How to check if a package is installed in android Kotlin programmatically for android 12+?

private fun isAvailable(ctx: Context, intent: Intent?): Boolean {
    val mgr = ctx.packageManager
    val list = mgr.queryIntentActivities(intent!!, PackageManager.MATCH_DEFAULT_ONLY)
    return list.size > 0
}

Use this code snippet for that, Thanks.
