Successfully in terms of communication or in terms of security?
Successful communication is easy if you don't worry about security. Just post it on Instagram.
How do you know if your security is successful? How do you know if your messages were intercepted and read, your app was hacked, data was extracted from it, etc.? The attackers (authorities or otherwise) are not going to tell you.
If you attend, leave your phone home (atypical usage), go with other people / meet them there / other people you know are there (facial recognition / gait analysis / clothing preference) those are all good data points to predict with high probability where you are and what you’re up to, especially given your typical movements, data usage patterns, purchasing habits, friends / acquaintances / social media interactions are all in at least a few databases.
Take the security measures you’re willing to make the tradeoffs for.
If history is anything to go by, we’re only ever an election, or other political churn, away from your particular sets of beliefs / identifiers being persecuted, or at least your least favourite political prisoners being released and coming after you.
And, as you allude to, relying on the security practices of others has its own problems. Even Perfect Forward Secrecy etc etc provides little help against Rubber Hose Cryptography.
it goes other way around too - you are only one election cycle away to be pardoned.
And if the protest is succrssfull, you dont need a pardon anyway.

Nope, assume Meta is captured and will suppress such communication.

This has been widely replicated on inauguration day before being rolled back.
I would assume any social media site whose CEO attended is captured as well.
