Please help! Frequently used emojis?

for the past few days now, some really random emojis have been appearing in my frequently used on my XS Max. At first I thought nothing of it, but now I am getting pretty freaked out over it.

This is seriously weird, and I have NEVER used these emojis (until now in this post), and I haven’t even accidentally tapped them! I don’t even share an account with anybody, and nobody has access to the account. I haven’t even been alerted of my account being breached or anything like that, and my password hasn’t been changed by anyone. Does anybody have a possible explanation of what this could be? Hackers? A virus? Just a glitch? Thank you in advance!
