I try to suggest consistent translation with Android and IOS version. I have other suggestion but it will differ with the Android and iOS. Currently there is no applied translation in TDesktop.

If we have to change other apps translation which already applied to production, it will be counterproductive. But if we refer to translation style guideline in home page of https://translations.telegram.org/ , we also need to see what other apps like has translated. I barely see the word "Channel" to be "Channel" . Moreover, the word "Channel" is not officially registered in KBBI (Legal Dictionary of Bahasa)
