Question: inequality in animate

hi, is there any option to make inequality in animate with filled/marked area?

restart;
with(plots);
display(animate(implicitplot, [abs(x + y*I - a) <= 2*(1 - abs(x + y*I)), x = -2 .. 2, y = -2 .. 2], a = -1.75 .. 1.75, frames = 100), implicitplot(x^2 + y^2 = 1, x = -2 .. 2, y = -2 .. 2, color = black));
