Reparación Y Conexion De Extensión Chrome - Crm Whatsapp

Hello sir.
I would like to please quote the repair of my Google Chrome extension. It is a crm for whatsapp
i have in the back end source code, the panel for the assignment of users and resellers. And also with the extension.
However, I have had problems connecting it.
I have 2 versions "basic and full premium"
in the basic extension, due to the last whatsapp update i could not correct the errors and it has loading problems.
In the second extension I have 5 problems:
First. The GPT chat function and connection does not work, it does not validate any code.
Second. The signature editing option also does not work and does not validate the information.
Third. The quick reply function crashes when trying to upload a video or image.
Fourth. Although it connects to Google Calendar, it is not possible to save contacts from the extension and the functions are limited.
Fifth. When I try to connect my Google account, I get this notice with their contact information from another company.

I appreciate your kind response and quote for the repair.

I also need to be able to upload to the Google Web Store so that the extension can be uploaded to the Google Store
