Share files via Intent from android

Hi there!
I have a problem. My app has function for shareing image + text via Intent, but when i'm choosing dropbox it shareing only image or only text.

val shareIntent = Intent()
        shareIntent.action = Intent.ACTION_SEND
        when {
            imageUri.isNotEmpty() -> {
                shareIntent.putExtra(Intent.EXTRA_STREAM, imageUri)
                shareIntent.type = "image/*"
            }
            else -> shareIntent.type = "text/plain"
        }
        shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
        shareIntent.putExtra(Intent.EXTRA_TEXT, text)
        startActivity(Intent.createChooser(shareIntent, "Share images..."))

That is how i'm shareing files. What's wrong and what should i do?
