Updating Multi-Select fields is currently not supported by the Box SDK

• I have checked that the SDK documentation and API documentation doesn't solve my issue

Description of the Issue

I have run into some issues using the Box SDK to update the metadata of fields that are new multi-select values. I can retrieve them easily enough.
I can not seem to find a feature on the Metadata object that allows you to set the field as directed in the link below. I have looked through the documentation and there are no examples I could find.

There seems to be no way to set the value of a path to a JsonArray (or array of strings) on the Metadata class. I have upgraded my Java version of the SDK to 2.17.0

Steps to Reproduce

This is best done with a unit test.
Create a metadata template on box with a multiselect field.
Assign the metadata to a file on box.
Create a unit test that will retrieve the metadata from the file.
Attempt to change the field using Jave on the Metadata class instance returned from box.

Hi @stuart-erskine — this functionality was just added to the API and we haven't added it to the SDK yet! It should be pretty straightforward though; I'll try to get it done in the next couple days. I'll update this issue when it's being added.
