Existe alguma forma de não exibir meu nome de usuário no URL do formulário?

If I understand your question correctly, you don't want to show your username in URL.

Unfortunately,it is not possible to remove your username in the custom URL. However, you can use another text. To do that, we need to change your username.

If you want to use your own  custom domain, alternatively, you can use ''Çustom Domain'' feature. To do that, please check the guide below for more information:
