ANDROID: How to see/debug recaptcha sitekey of an apk?

Question

Dears,

I'm trying to find the sitekey parameter configuration of a repacha Android API apk.

I'm using Android Emulator a have installed the Apk from Play Store. Running apk, in some moments it shows recaptcha form. I need the sitekey parameter of this form... how can I find that? Like view source of a webpage.

Bellow the screen in the moment: recaptcha

Bellow the screen in Appium, but I dont find any information in source: enter image description here

Bellow the code to implement google API recaptcha ind Android, allegedly used by the developers of the apk:

    fun onClick(view: View) {
        SafetyNet.getClient(this).verifyWithRecaptcha(YOUR_API_SITE_KEY)
                .addOnSuccessListener(this as Executor, OnSuccessListener { response ->
                    // Indicates communication with reCAPTCHA service was
                    // successful.
                    val userResponseToken = response.tokenResult
                    if (response.tokenResult?.isNotEmpty() == true) {
                        // Validate the user response token using the
                        // reCAPTCHA siteverify API.
                    }
                })
                .addOnFailureListener(this as Executor, OnFailureListener { e ->
                    if (e is ApiException) {
                        // An error occurred when communicating with the
                        // reCAPTCHA service. Refer to the status code to
                        // handle the error appropriately.
                        Log.d(TAG, "Error: ${CommonStatusCodes.getStatusCodeString(e.statusCode)}")
                    } else {
                        // A different, unknown type of error occurred.
                        Log.d(TAG, "Error: ${e.message}")
                    }
                })
    }

Is there any software to find what is YOUR_API_SITE_KEY parameter used when Apk is running? I'm not the apk developer.

With this, I'll try to by-pass captcha using Appium an one of services bellow:

2Captcha
Kolotibablo
protypers
megatypers
qlinkgroup
captchatypers
