Update specific attributes of an existing asset field using the update_mask parameter to control which properties are modified.

• If update_mask=name, only the name is updated regardless of other values in the request body.
• If update_mask=select_options, only select options are updated.
• Multiple attributes can be updated in one request using comma-separated values: update_mask=name,select_options.
• Any attributes not listed in update_mask are ignored, even if present in the request body.

When updating select options:

• New options can be added to the select_options array.
• Existing options cannot be removed or modified (to preserve data integrity on existing assets).
• Total options cannot exceed 100.
• Each new option requires a unique id and label.

• SafetyCulture Premium Plan or Enterprise Plan
• "Assets: Manage" permission
