Oh, after a while I gave up and resorted to copy paste the phone/mail emojis. 😅 what I was trying to achieve was using a custom image for the phone/mail however the image in question couldn't keep the size so it made the announcement bar to enlarge or the image would become very small were you could barely see it.
I added the phone Icon back into the announcement bar so you can see! thank you for looking into it! 🙂
