If you mean the case where he raised presidential immunity against seditious conspiracy charges?

The reason he was granted this is because in his capacity of president, basically the courts are supposed to cut him some slack if he does some accidental criming; you see, if the president does it, it’s usually necessary to perform his duties and if you stop him you are preventing him from getting any work done. That’s basically what the supreme Court ruled. It’s a bit like when cops raise qualified immunity. It’s supposed to insulate them from personal grievances so they are able perform their duties. Only that the presidential immunity is way worse for us, because a cop can raise it and then prosecution has the burden to prove there was a rule and the cop knew it. But in this case it’s worse because the president just has to say it was in his presidential capacity and that’s it iirc.

So back to your question: can you do so too? No. You are not a president, you don’t have presidential immunity.
