Was the "I" in the novel the author? If the author's real name appears, then is "I" the author?

Usually, the " I " in the novel was not the author, but the pen name or real name used by the author when creating the work. In the process of writing a novel, authors may use multiple pen names or real names to protect their privacy or avoid conflicts with other authors. If the author's real name is the same as the pen name used in the novel, then I may be regarded as the author of the novel. However, this was only one situation and could not be used as an absolute standard. In some cases, authors might hide their real names in their works to protect their identities. The identity of the author of a novel might vary from novel to novel. In the process of writing a novel, the author may use multiple pen names or real names, or may hide their real names in the work or expose them to the sun. Therefore, it is impossible to determine whether I am the author of the novel. I need to analyze the specific situation.
