write google app script code to customize a google forms survey

Hello, I have a survey in Google forms 30 questions, one of the parameters of my survey analysis, it is necessary to accurately measure the time to take each respondent to answer each individual question in seconds, I did not find any native option in Google forms that It allows me to measure the individual response time or other platforms of the surveys, the same time that can be measured the time it took the respondent to answer the whole survey but not to each specific question, as well as someone who can add a timer The application of the script of the Google application would be great.
