问题
I'm creating a Gmail add-on and one of the use cases is that user could define a server URL from which the data should be fetched. However, the URL always will have trailing part in the domain name
https:// [part which user defines] .my.domain.com
Currently, there is no option to deploy Gmail add-on without providing the urlFetchWhitelist list. In my case, I can specify the end part of the whitelisted URLs, whereas the GAS gives only define prefix
Are there any approaches how to define some pattern for the urlFetchWhitelist?
