You are reviewing a third party extension for Magento Commerce Cloud compatibility. You discover the module writes to a custom directory called internal/ within the Magento base directory.
The directory has to be shared by all web servers.
What do you do so the module can be used on Magento Commerce Cloud?
A. Create a symlink from /tmp/internal to the internal/ folder
B. Declare a shared mount for the internal/ directory in .magento.app.yaml
C. Request the vendor make the directory configurable in the Magento admin
D. Add a patch for extension so it uses the subdirectory var/internal/ instead
