Is WRC Plus free?

Could you please clarify if the WRC Plus service is offered at no cost to users? It's essential for our audience to understand if they can access the platform and its features without any financial commitment. We're particularly interested in knowing if the basic functionalities, such as live streaming of races and on-demand content, are included in the free version. Additionally, is there a premium tier that offers additional benefits, and if so, what are those benefits and their associated costs? Thank you for your assistance in providing this information.
