No, it's not.

Describe the solution you'd like
As a flinkey integration partner I want to have the possibility to easily integrate install/uninstall product to/from car into my solution without building entire new UI for it.

Additional context
flinkey API Endpoints we need to use:

• Get cars (also note that there's OData querying available for this endpoint)
• Get products (also note that there's OData querying available for this endpoint)
• Install product into car
• Uninstall product from car
