When sharing data in Snowflake, the provider needs to grant the following privileges along with a share:
* A. USAGE on the specific tables in the database: This privilege allows the consumers of the share to access the specific tables included in the share.
* D. USAGE on the database and the schema containing the tables to share: This privilege is necessary for the consumers to access the database and schema levels, enabling them to access the tables within those schemas.
These privileges are crucial for setting up secure and controlled access to the shared data, ensuring that only authorized users can access the specified resources.

Assigning the custom role to the SYSADMIN role is considered a best practice because it allows the SYSADMIN role to manage objects created by the custom role. This is important for maintaining proper access control and ensuring that the SYSADMIN can perform necessary administrative tasks on objects created by users with the custom role.
