For the integral shown below, how do I get Mathematica to output only the "correct" answer as 1 (for future steps in the notebook) and i.e. have Mathematica NOT OUTPUT the ConditionalExpresssion that q2 is real etc?

In[5]:= Integrate[DiracDelta[p - q2], {p, -Infinity, Infinity}]

Out[5]:= ConditionalExpression[1, q2 \[Element] Reals]
