# Extra white line in densityplot's output

How can I remove the white line in $$y=0$$? This is my code:

Rc = 0.1;
m = 0;
foo[Rp_?NumericQ, tep_?NumericQ] :=
NIntegrate[-Sin[tp] Exp[- Cos[ (tp - tep)]], {tp, 0, 2 Pi}]
DensityPlot[
foo[Sqrt[x^2 + y^2], ArcTan[x, y]], {x, y} \[Element]
Region[RegionDifference[Disk[{0, 0}, 2.3], Disk[{0, 0}, 0.8]]],
PlotLegends -> Automatic, ColorFunction -> "Rainbow",
PlotRange -> All, PlotRange -> {{-2.3, 2.3}, {-2.3, 2.3}, All}]
