Deriving transfer function from Bode Diagram

From the Bode Diagram which is also a minimum phase system,

I have tried to figure out the transfer function it could have been like this,

$$ \begin{align*} L(s) = \dfrac{1}{s}\cdot\dfrac{2}{s + \sqrt{2}} \end{align*}$$

Which, I see that there are two different slopes in the graph, I guess there are two poles in the transfer function. Besides, the frequency at 1 and root 2 are also the points to identify the coefficients of the transfer function. Thus, I guess this should be the approximated function. However, I use Wolfram to plot the bode diagram of this function, it does not correspond with the graph shown here.

What could be the incorrect guess about the derived transfer function?
