Auto restrict members on Telegram crypto group

[CryptoC7]

Hi guys, I want to start a crypto related group on Telegram but does anyone know how to automatically restrict members as soon as they join the group? I know we can manually restrict members through the telegram settings but is there any bot which could auto-restrict them so that they can only have a read-only mode in the group. Basically i want the group to function as a channel (the reason i am not creating a channel is that software like telegram auto work only for the groups).

Any help or guidance will be highly appreciated. Thanks!
