Android - ShareActionProvider Share Menu add particular option

问题

This is what I have:

val imgURL = "https://blaaaa.com/pic.jpg"

val shareIntent = Intent()
shareIntent.action = Intent.ACTION_SEND
shareIntent.type = "text/plain"

shareIntent.putExtra(
    Intent.EXTRA_TEXT,
    context.getString(R.string.check_this_out) + " " + domain + "/post/?id=" + meme.id
)

context.startActivity(
    Intent.createChooser(
        shareIntent,
        context.getString(R.string.send_to)
    )
)

This way I'm sending a text to any available app in the share menu.

But I need to add one PARTICULAR option that doesn't send the text but opens a new activity called DownloadImage and sends the string imgURL to it.

Like this:

This doc: https://developer.android.com/training/sharing/send#adding-custom-targets isn't helping because it only shows how to change the content type that is sent to all apps globally.

I've seen this in other apps so this is possible.
