Sunflower lanyard

I‘m debating getting a sunflower lanyard after doing some research. I struggle in my day to day life with various sensory issues and in public spaces I could do with people being mindful that I have a hidden disability (autism) and exercise patience and not assume that I’m being rude in certain social situations. I‘m also considering wearing one for my new job as I will be in a public facing role. I feel this may be beneficial for me as I know some of my autistic traits can be taken the wrong way by neurotypical folk so maybe having the lanyard would help with this especially as I only just got my autism diagnosis and I’m not confident with disclosing it to most people. I thought I would ask here people’s experience with using the lanyard as some first hand accounts may help with it it will be a useful tool for me.
