According to the docs, searching file content using a query (not just filenames) with files_search() requires a "Dropbox Business account". However, that requirement isn't mentioned anywhere else in the python-sdk documentation.
Should I assume that it's required to perform my desired task for files_search_v2 as well? And if so, how can I proceed with upgrading to Business? I would like to only pay the minimum needed to get access to file content querying with the API.
