Share Intent for dynamic image in imageview without saving, using kotlin with little permissions as possible

Question

I need to share the image in the imageView and the following code is promising (though not quite what I ) but returns some errors:

Kotlin:

    fun shareImage (iv: ImageView){
        val bitmap: Bitmap = iv.drawToBitmap()
        val imageName = "/image.jpg"
        try {
            File(this.cacheDir, "images").deleteRecursively()
            val cachePath = File(this.cacheDir, "images")
            cachePath.mkdirs()
            val stream = FileOutputStream("$cachePath$imageName")
            bitmap.compress(
                Bitmap.CompressFormat.JPEG,90,stream)
            stream.close()
        } catch (ex: Exception) {}

        // SHARE
        val imagePath = File(this.cacheDir, "images")
        val newFile = File(imagePath, imageName)
        val contentUri = FileProvider.getUriForFile(
            Objects.requireNonNull(getApplicationContext()),
            BuildConfig.APPLICATION_ID + ".provider", newFile);


        if (contentUri != null) {
            val shareIntent = Intent()
            shareIntent.action = Intent.ACTION_SEND
            shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
            shareIntent.type ="image/jpeg"
            shareIntent.putExtra(Intent.EXTRA_STREAM, contentUri)
            shareIntent.putExtra(Intent.EXTRA_TEXT, "This is a file for share")
            startActivity(Intent.createChooser(shareIntent, "Choose app"))
            grantUriPermission(
                packageName,
                contentUri,
                Intent.FLAG_GRANT_WRITE_URI_PERMISSION or Intent.FLAG_GRANT_READ_URI_PERMISSION
            )

        }
    }

Manifest:

    <provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/filepaths" />
    </provider>

filepaths xml:

<paths>
    <external-path
        name="external"
        path="." />
    <external-files-path
        name="external_files"
        path="." />
    <cache-path
        name="cache"
        path="." />
    <external-cache-path
        name="external_cache"
        path="." />
    <files-path
        name="files"
        path="." />
</paths>

Result:

Even this doesn't work but it is not even close to what I require. I need to share the image in the imageView with 2022 Kotlin code (e.g. in previous popular answers MediaStore.Images.Media.insertImage is deprecated) without necessarily saving to device or at least without accessing external files.

I am having a hard time believing this is not a realistic expectation.
