How do I pay the Elis fee online?

Excuse me, I'm trying to understand the process of paying the Elis fee online. Could you please guide me through the steps? I'm not familiar with the platform and would appreciate it if you could explain it in simple terms. Is there a specific website or portal I should visit to initiate the payment? Also, do I need to have any particular cryptocurrency or payment method ready? Lastly, are there any fees or charges associated with the payment process? Thank you for your help.
