CLS filter question

Hello. I am a starter astrophotographer and i just got my CLS filter. When i tried it out on the Orion nebula, it looks like there were no results. The photos i took were from my phone, 2s exposure each, from Levenhuk BASE 110s. The 1st photo is with the filter and the 2nd is without. Am i doing something wrong or is it not how filters work?
