How to set the SMS verification code to fill in automatically for Huawei mobile phones?

There is no automatic recharge function, which is for the safety of funds in your mobile phone. For example, some games send you a verification code, but you can't fill it in yourself. If you fill it out automatically, there will be a charge. There is also a pocket bank, which automatically fills in the verification code. If you turn wrong, there will be no reaction time. If you receive the verification code, you can copy and paste it. Automatic filling is risky.
