How do I bypass permission on Applications on Macbooks?

Now, i'm not posting this because of a game. I have a youtube channel, and I bought a screen recorder on my school Macbook, as that was the only thing I could use for it. Recently, my district installed something that blocks almost all applications. Including my screen recorder. Whenever I try to open it it says I don't have permission to use the application. Is there any way to bypass this? I just want to keep making videos, and I don't want the money I spent on the screen recorder to go to waste. Thanks in advance!

Your school owns the Macbook and can put whatever restrictions they want on it (same my work Macbook Pro). We are not going to discuss bypassing those restrictions.
