Olá, quero instalar o Pendo ([pendo.io](http://pendo.io) - analytics)
Procurei informações mas não consegui encontrar.
Alguém poderia me ajudar?

Bem-vindo Daniel! 👋
Eu não conheço o Pendo, mas se for apenas um trecho de JavaScript que precisa ser adicionado, você deve conseguir adicioná-lo no painel de administração do seu Discourse:
Personalizar → Temas (ou Componentes, que pode ser mais prático para criar um novo se o seu fórum tiver vários temas) → Editar CSS/HTML → aba `Head`.
Me diga se o Pendo precisa de mais do que isso 🙂

Obrigado! Dicas muito úteis.
Agora, como posso alterar a `content_security_policy` ou o que posso fazer para corrigir isso:
Estou recebendo um erro no console que diz:
```plaintext
head_tag_1.js:7 Refused to load the script 'https://cdn.pendo.io...' because it violates the following Content Security Policy directive: "..." . Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.
```

Olá @dafegosa,
Eu _acho_ que a opção 1 nas configurações do site, conforme descrito nesta seção do tópico Política de Segurança de Conteúdo, pode funcionar para o que você está tentando fazer, mas se não funcionar, há muitas informações boas no tópico:
