How can we apply hold on Order line entity in a Sales Order using Rest API

Summary:

Hello experts,

We are currently using the Receive Order Request Service to apply and release holds at the order line entity level using OIC at regular intervals.

Since the Receive Order Request Service is deprecated, we are trying to switch to REST API. However, with the REST resources below, we are only able to apply holds on the fulfillment line entity, and we are unable to apply holds on the order line entity.
