@Deus tried and it works! Thank you 
Cool! Glad it worked 🙂
Happy to know that I could be of ‘service’ to someone who taught me a lot when I started out with Mastodon and the Fediverse 🙌

@Deus there is an old Chinese saying goes: "The real fact is that one might have learned the doctrine earlier than the other, or might be a master in his own special field." Translating it into English is challenging as its elegance in Chinese. Nevertheless, your solution has truly been immensely helpful to me😄
Mashiro - No big deal. You too were patient enough with teaching me the steps of how the Federated network works. And of course, the many screenshots (with arrows) exchanged in between. Glad that Bing translate was always there to help 😁
