Walking in front of a person who’s praying

So I was really sad about a certain situation which is why I was very absent-minded and I walked into the bedroom without paying attention & I accidentally laid down on the bed without noticing that I was right in front of one of my family members who was praying. I immediately walked away but now I wanna know do I have to do anything else except repenting? Do I have to apologize to the person? Do they have to do anything?
