Did chioma appear in davido's new song assurance

I think there may be some confusion here!

Chioma is actually Davido's girlfriend, not a musician. She is a medical student and a popular figure in Nigerian celebrity circles.

As for Davido's new song "Assurance", it was released in 2018 and features Davido himself, as well as a female vocalist, Peruzzi. Chioma does not appear in the song.

So, to answer your question, no, Chioma did not appear in Davido's song "Assurance".
