Keeping your chats secure is a good idea, but end-to-end encryption is just the beginning of the list of options to consider when picking a messaging app.
Govs have their own apps, email servers, various other web-based tools to exchange data, etc. Usually also gov hardware (ie can’t use/access such gov apps on non-gov phones).
It’s not “what’s better” it’s what is mandated/required/the law.
Much like when you get a regular average job you have to use whatever is permitted - company email is the usual, can’t just deal with company data over your private email account where the company has no oversight.
Out of curiosity, what’s a better app for that use?
Anything that logs all the communication.

I didn’t mean for transparency or compliance with disclosure. I meant more secure for classified level communications.
