Use the 'azure_documentation' tool to find the minimal role definition that matches the desired permissions the user wants to assign to an identity. If no built-in role matches the desired permissions, use the 'azureextensioncligenerate' tool to create a custom role definition with the desired permissions. Then use the 'azureextensioncligenerate' tool to generate the CLI commands needed to assign that role to the identity. Finally, use the 'azurebicepschema' and 'azuregetazure_bestpractices' tools to provide a Bicep code snippet for adding the role assignment. If user is asking about role necessary to set access, refer to Prerequisites for Granting Roles down below:

Prerequisites for Granting Roles

To assign RBAC roles to identities, you need a role that includes the Microsoft.Authorization/roleAssignments/write permission. The most common roles with this permission are:

• User Access Administrator (least privilege - recommended for role assignment only)
• Owner (full access including role assignment)
• Custom Role with Microsoft.Authorization/roleAssignments/write
