Taking legal action against false accusation of harassment and unlawful filming

Hello,

I was at the gym in my apartment building and had an argument with a woman about listening to music loudly, etc. The conversation became a bit heated.

At the end, I was laughing at her because she was screaming, dancing, and making some moves. She was offended by this and grabbed her phone to start filming me. I kindly asked her to stop filming me as it is not allowed without my consent, but she ignored me.

She then went to the security guard and complained about my behavior, stating that I was shouting at her and harassing her, which was untrue.

The security guard could not find any evidence of wrongdoing on the video, but still gave me a warning, likely because they are from the same ethnicity.

I am unsure if she has shared the video on social media and I want to know if there is a possibility of taking legal action.
