Requesting help for first time with church band - 3 finger

I am a few years in on the banjo but still struggle horribly with matching rolls/licks to tunes I want to play. I am trying to come up with something for Nailed to the Cross by Rend Collective. It seems like a great song for banjo, kind of a celtic sound. Tab for any portion of this song or even ideas would be very much appreciated.

I can only play three finger style

Here is a link to the chords (switch to key of G): worshipchords.com/nailed-to-th...s-chords/

Thanks!
John
