Currently, it's available on the Vercel marketplace and accessible via the following URL: https://vercel.com/marketplace/vezlo-assistant-server. However, it won't be searchable until it reaches 500 installs, as per the official Vercel documentation here: https://vercel.com/docs/integrations/create-integration#connectable-account-integrations.
Once there are more than 500 active installations, it must be sent for approval to Vercel by following and completing all the review guidelines, so it becomes available on the public page as well.
