So I am trying to use Animate for my 3D Plot, to see how the function changes with respect to time. But for some reason the z axis keeps rescaling such that the function appears to be constant (but isn't actually). My question is: Is it possible to fix the axis? if yes, how? Here is my code:

uh[x_, y_, t_] = 1 + E^(-2 t)*Sin[x]*Sin[y];
Animate[Plot3D[uh[x, y, t], {x, -2 π, 2 π}, {y, -2 π, 2 π}], {t, 0, π}, AnimationRunning -> False]

Thanks in advance

uh[x_, y_, t_] = 1 + E^(-2 t)*Sin[x]*Sin[y];
Animate[Plot3D[
  uh[x, y, t], {x, -2 π, 2 π}, {y, -2 π, 2 π}, 
  PlotRange -> {0, 2}, BoxRatios -> 1, 
  PerformanceGoal -> "Quality"], {t, 0, π}, 
 AnimationRunning -> True, AnimationDirection -> ForwardBackward]
