Given the function $f\left(x\right)=e^{x}-mx-1$, where $m \gt 0$.  
$(1)$ If the tangent line of the graph of the function $y=f\left(x\right)$ at the point $\left(0,f\left(0\right)\right)$ is $y=0$, find the value of the real number $m$.  
$(2)$ Find the monotonic intervals and extreme values of the function $y=f\left(x\right)$, and provide the reasoning.
