Hello, I have a website, let this website be https://wmaraci.com. The homepage of Wmaraci includes blog and article news, doesn't it? Whereas, https://wmaraci.com/forum consists of a forum structure and forum system. Currently, my https://wmaraci.com main directory is running WordPress. In the https://wmaraci.com/forum directory, Xenforo forum platform is installed. Since my WordPress automatically generates the sitemap, I am unable to create the sitemap for the /forum section myself. As the https://wmaraci.com/forum directory is a separate subpage, how should I submit its sitemap? How can I show it to Google? Thank you. In summary, I need to submit multiple sitemaps, how can I do it?
