Plotly Add text at specific position on a chart

I am trying to add some values below the x-axis labels as in the pic below. I am able to achieve that using the break tag as needed. However, the I need to add label ‘Date’,‘Last 3weeks average daily forecast accuracy’ at the specific position shown. I tried using simple annotations, annotations on data and even tried adding the labels to the first x axis label and trying to shift it but I couldn’t shift it to the left.
This what I want
This is where I am
How can I do this? Thanks in advance
