Power of the two-sided normal LRT

Let $X$ be a random variable having $N(\theta,1)$ distribution, where $\theta\in\mathbb{R}$. Consider testing $H_{0}:\theta=0$ against $H_{1}:\theta\neq 0$ at $\alpha=0.617$ level of significance. The power of the likelihood ratio test at $\theta=1$ equals __________ (round off to two decimal places)
