Aside from introducing custom wallpapers, it's now easier to share chat folders on Telegram. The app lets you invite friends and colleagues to work groups, news channels, and more using a link. With one tap, they can access a chat folder and instantly join all the chats.
When creating a link, you can select the chats you'd like to include and give them a unique name to match. You can include any public chats or those where you have admin rights to add people. If you add more chats to your folder and update the links, the members will see a suggestion to join the new chats. If you haven't created a folder before, you can open Settings > Chat Folders.
