Rules for using periods with bullet points

If you're writing a CIM or some other document on PowerPoint, do you use periods after bullet points that are full sentences? I know this is such a simple and dumb question, but in my company and region, we use punctuation in our native language but not in English. All sources that I find online say that you should use punctuation with bullet points that are full sentences (when writing English), but I'm not sure if the punctuation practices are different in finance context / PowerPoint.
