I think it’s fine to describe the legislation you advocated for, as long as it doesn’t veer too far into controversial topics. As a very general illustration of this, mandating cross walks in shopping areas is probably a safe bet, whereas banning CRT in public education probably is not. Keep it general rather than specific, because your word count is probably tight in this type of essay anyway. Unless all the detail is needed for some reason, make sure you’re answering the prompt above all else.
And if you are just talking about the activities section, you’re limited to 150 characters, so make the focus on your purpose, rather than detailing the legislation itself.
