Sorry if you already move on from this. I don't know much about Nicaragua to say if you will have any luck with trying to ask the local government for help. However, I lived in a third world country before where if you escalate to the local government, all they do is shrug their shoulder and ask you to move on. Unless you are rich and powerful enough, which would negate all of these problem from even happening from the beginning, to have somebody in the "local government" to help then that road is typically a dead end.
Other stuff you can try is directly appealing to the working crews. Just a little bit of food and some greetings would sometimes give you a lot of information regarding who they are, who they are working for and what they are doing. If you know who they are working for, you can then go and appeal to them, which might solve your issue (or make it worse), but try to asset before reaching out just in-case. Knowing the crew might also reduce the annoyance since people tend to be more considerate around people they know. However, it might not help much if the crew is also under pressure and constraint from their contracts and workload.
There is two problems with this conflict though. Firstly, the way that Lelouch built a resistance against his brother was not to win back his old allies and prove to them his trust worthiness, but by magically flip the whole chessboard and turn every Britannian into a mind slave willingly do his bidding. That sounds exactly like liberal fantasy fixing the system and transform it into a force for good. Secondly, Schneizel also did a board flip and get everyone on the rebel group to support him as their leader for a war which essentially is just a fight for the throne of the world. The rebel even complicit in a nuclear first strike attack on the Britannian capital which have unknown number of civilian in it.
This plot point however shine the spot light on the structural problem of the whole rebels. They are just a bunch of people with no unified ideology that can let them look pass the fear of the power of geass to even offer Lelouch a chance to explain himself. They don't even offer him a real trial before trying to gun him down in cold blood. While I'm sure there are many example in real life where people flipped out and assassinated their political leaders for less. The story decision here to let Lelouch be saved not by the quality of his ideology, or any of his policies but just purely because another broken and exploited character clung onto him and bailed him out with their life speak a lot for the quality of the rebels leadership and ideology.
That's my main problem with Code Geass to be honest. Overall, it's an entertaining show with the facade of anti-colonialism, anti-imperialism, pretty twisting story line and some awesome mecha battle. However, the show stop short of offering any true solutions to the problems and instead just outright prescript great person theory and enlightenment dictatorship to imperialism. It doesn't even have any representation for communism, anarchism or any more leftist groups. Instead, we had an imperial capitalist monarchism vs a bunch of nationalist monarchist of a different religion vs some liberal democracies in the background.
