Shouldn't they then use Congress as intended rather than what they're doing now which bypasses it?

As a bystander in another country your line of argument is mind-boggling. You don't just throw out the constitution and way the government works because one guy won an election one time. But that seems to be what a lot of people are suggesting, that because Trump won the election whatever he does is democratic and therefore okay.

And secondly no, Trump also publicly lied about his positions by saying he had nothing to do with Project 2025.

But it doesn't matter if he did say the truth anyways, saying that you'll make a coup doesn't make the coup okay.
