How to paste autosuggested code from keyboard in different textinput field -Android

Question

Currently, the issue is clicking on autosuggested text only filling the first textinput box, I want to fill all the six text inputs with the suggested code

On clicking the autosuggested text, it is only filling first

Expected behaviour is to fill all the textinputs once user clicks on autosuggested code

This is a less explored use-case on StackOverflow, but, when you read Android docs for Auto-fill, in the OTP section, they have already provided generateSmsOtpHintForCharacterPosition which states and I quote:

When using multiple views where each view maps to a single digit of the OTP, you can use the generateSmsOptHintForCharacterPosition() method to generate per-character hints.

You can utilize the characterPosition parameter to auto-fill each EditText with the respective digit of the OTP auto-filled.

To do that, set

//Where Character Position (int) represents the digit position of the OTP for respective EditText, ranges from 1 to 8.
android:autofillHint="smsOTPCode{characterPosition}"
