The most common form of Multiplexing is often thought of as “connection pooling”, where many users are accessing an application through a single contact point. As technology in the world has advanced, there are many other forms of Multiplexing that have emerged, such as automated processes to migrate data, accessing applications indirectly, and more. Multiplexing does not reduce the number of subscription licenses of any type required to access the Power Platform services. Any user or device that inputs data into, queries, views data from or otherwise accesses Power Apps, Power Automate, Power Virtual Agents and Power Pages apps, directly or indirectly must be properly licensed. The number of tiers of hardware or software between with Power Platform apps and the users or devices that ultimately use Power Platform indirectly does not affect the number of User SLs required. For additional information about multiplexing refer to the Microsoft Multiplexing Overview. (Licensing Documents (microsoft.com))

Regardless of the device being used, if a given organisation is benefitting from the existence / usage of Java then that organisation needs to subscriptions in place assuming the OTN Java SE agreement doesn’t cover their usage
