thank you for adding google sheets/push feature... I'm very happy to see this :)
Please, can you finish verifying your app/connection with google(it throws an warning)
Also, please adjust your permissions with sheets to only allow 'create'... not veiw, and delete... I'm not sure why you need these in your solution
Lastly :) - please add customer + installer descriptions into the sheet... either as a second workbook or an additional line at the top
Thank you and keep up the great work!
