BIF AF Confusion with R7, RF 100-400mm Rf 1.4x

I having difficulties using AF for BIF with my R7 with the RF 100-400mm and RF 1.4 x attached.  I think I was using one of the smaller AF selections such as center, center expanded, etc.  The wide horizontal did seem to work better but not as good as I expected.  I  tried 2, 4 and auto as behavior for AF.

I couldn't even find a bald eagle flying towards me with a light sky.  I had no problem when using my 5DMKIV with my 300mm f2.8 and 2x.  Of course the 5DMKIV is a through the lens optical view and the R7 is mirrorless, but I thought that I'd still be able to use it to find BIF photography.

What method are others using?
