Worried I’ve committed shirk?

this is my first post on this site so I hope it’s okay. Basically, a while ago my friend (Hindu) invited me to her place during a festival period for Hindus. I then found out we were going to visit the temple so I just thought I would go with them and they would pray and we’d leave but obviously I wouldn’t pray because it was more of a cultural thing for me to learn about their festival. However, it turns out the thing at the temple was actually a celebration for the festival and they were doing some kind of traditional dance and my friend asked me to take part so I did cause like I said, I was intrigued with the culture and what they were doing. I didn’t realise until later the thing they (and I) had been dancing around was an image of one of the Hindu Gods they believe in but I got too anxious to say anything and I continued dancing with my friend because in my mind, I didn’t believe religiously in anything they were doing and obviously knew Allah was and is the only God I believe in and worship. At the end of the night is when everyone in the temple started praying but I didn’t take part and when they all went to get a blessing from their God I didn’t go and even when one of the ladies asked me to I said no because that’s not the God I believe in. Looking back, I regret taking part and I know it was wrong but I’m worried that I committed shirk through my actions though in my heart I didn’t believe in their beliefs. I‘ve been making tawbah but I’m really worried and am hoping someone can calm my nerves :(
