Android Jetpack Compose: Unresolved reference: Intent

I've been building an app entirely with Jetpack Compose and I have noticed that in the last 3 o 4 canary versions of the Android Studio, the tools are getting worse and worse (at least for me) because I can see now CPU at 200% and especially, missing references.

So I have a Toolbar component and I have an action to share a certain screen with other uses by using Intent.createChooser. This is already working, because I created it with previous versions of the AS Canary but now, always get the following error:

Unresolved reference: Intent
Unresolved reference: action
Unresolved reference: putExtra
Unresolved reference: type

This is the code I'm using inside my TopAppBar:

actions = {
            if (addShareButton) {
                val context = AmbientContext.current
                IconButton(
                    onClick = {
                        viewState.job?.let {
                            val sendIntent = Intent().apply {
                                action = Intent.ACTION_SEND
                                putExtra(Intent.EXTRA_TEXT, "I have found a remote job! ${it.url}")
                                type = "text/plain"
                            }
                            val shareIntent = Intent.createChooser(sendIntent, null)
                            context.startActivity(shareIntent)
                        }
                    },
                    modifier = Modifier.align(Alignment.CenterVertically)
                ) {
                    Icon(imageVector = Icons.Default.Share)
                }
            }

Also, AS gives a warning saying that the the variable context defined in the line val context = AmbientContext.current is never used, but it is in the line context.startActivity(shareIntent).

Am I doing something wrong? It is now impossible to code anything because of this and other errors.

Thanks in advance!
