            <intent-filter>
                <action android:name="android.intent.action.CALL_PRIVILEGED" />

                <category android:name="android.intent.category.DEFAULT" />

                <data android:scheme="tel" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.DIAL" />

                <data android:scheme="tel" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.DIAL" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.SEND" />
                <action android:name="android.intent.action.SENDTO" />

                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />

                <data android:scheme="sms" />
                <data android:scheme="smsto" />
                <data android:scheme="mms" />
                <data android:scheme="mmsto" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.SEND" />

                <category android:name="android.intent.category.DEFAULT" />

                <data android:mimeType="text/plain" />
            </intent-filter>
        </activity>

            <intent-filter android:priority="998">
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
                <action android:name="android.provider.Telephony.SMS_DELIVER" />

Answer 1

Add this in your manifest on top of(outside) <application tag>

<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />

Answer 2

If it is about OTP, for SMS retrieving you should be using Google's SMS retriever API,
