Description
If A visitor currently comes from ChatGPT to a website, ChatGPT might attach
utm_source=chatgpt.comto the url. Matomo and this plugin are currently not considering this parameter for new visits, if it can be detected as AI Assistant.However, if the
utm_sourceparameter persists, e.g. after page reload, the plugin might currently force a new visit. This should be avoided, unless new campaign parameters are provided, that don't resolve to an AI Assistant.fixes matomo-org/matomo#23708
