Can't click a numeric field and enter OTP in to it using Appium

Hi,
i am working on a native banking application. In one scenario while adding a beneficiary i need to insert OTP sent to the registered mobile number.as of now we have to pick the updated OTP from the database and insert it in the OTP field. OTP field is a numeric field.

driver.findElement(By.name(“Enter your”)).click();

while running the code, it is able to detect the OTP field but it’s not clicking it. (even device keypad is not popping up).

we tried with Xpath,ID,name,Tagname…but can’t click it.

how to overcome this scenario
