There are two steps to share access to your Odoo:
1. Share access to Odoo.sh project
This will help us to check your Odoo settings, help you to configure our products or debug an issue.
2. Share access to your repository
This will allow us to check third-party modules you have installed in your Odoo. Also, we will be able to push some fixes for bugs or updates for our products.
Please give us write access, if you want us to push updated or fixes. Otherwise, read access will be enough.
