Stuck in WelcomeActivity if permission is not granted

[raphaelm]

WelcomeActivity has a continue button that does this:

        binding.button?.setOnClickListener {
            if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED) {
                val intent = Intent(this, SetupActivity::class.java)
                startActivity(intent)
                finish()
            } else {
                checkPermission(Manifest.permission.CAMERA, PERMISSIONS_REQUEST_CAMERA)
            }
        }

This (suspectedly) gets you stuck if the permission is not granted and the system's rate limit for asking the user for the permissions is exceeded.
