i (18M) accidentally liked another girls story and she told my girlfriend (18F) what do i do?

okay so i believe this girl added me on IG. i followed her back to see if it was anyone i knew. by accident i must’ve liked one of her highlights of her when going through it without noticing. then unfollowed her knowing she wasn’t anyone i knew

fast forward to the next day and i have my girlfriend sad and rightfully devastated with a screenshot of my liking her highlight.

i explained to her it must’ve been by accident and told her i was trying to see if i knew her. i believe she believes me, she’s telling me that it’s put her off because it was scary having a girl dm her about her boyfriend. i was fully sympathetic and supportive. i believe ive handled this fuck up with maturity and well.

i’d like some insights or some opinions on what i could do or anything. thanks
