Grant workspace permissions to users or teams

This endpoint allows creating a grant which specifies permissions for one or more users or teams to access a workspace. ### Usage notes - **Grants**: An array of grant objects. Each object specifies a grantee and the permission level assigned to them. - Retrieve the **workspaceId** by calling the [/v2/workspaces](https://help.sigmacomputing.com/reference/list-workspaces) endpoint. - Do not set both **memberId** and **teamId** in the same **grantee** object. Instead, choose one based on the target of the grant. - Retrieve the **memberId** by calling the [/v2/members](https://help.sigmacomputing.com/reference/list-members) endpoint. - Retrieve the **teamId** by calling the [/v2/teams](https://help.sigmacomputing.com/reference/list-teams) endpoint. ### Usage scenarios - **Access control setup**: Use this endpoint to set up or modify access controls for a workspace, specifying which users or teams can access and what actions they can perform. ### Best practices - **Clear permission definitions**: Ensure that the permissions granted are well understood by both the grantor and the grantee to avoid misuse of access rights.
