Support StringCollection type for User Custom Attributes
Aside from String, also support StringCollection for custom-created user attributes on Azure AD B2C
We use Graph API to communicate with Azure B2C. Obviously we utilize custom attributes. However, due to lack of support Contains in search in string attributes, we feel very limited with options how to store the arrays that would be searchable. Introduce multiple custom attributes of the same meaning with index in name is not a good option.
Having support of stringCollection for User Custom Attributes is highly needed and will make life so much easier.
