Plotly: shareX between side-by-side plots

Question

I would like to have two side by side plots sharing the same X-axis and the same toolbar. This means that, by zooming in the first plot, the second plot should automatically resize to the same zoomed region.

A way to do that could be to stack the plots one above the other, using shareX=TRUE, but I need them to be side by side.

In python there seems to be a way to do that, using fig.update_xaxes(matches='x'). Is there a similar option in R?

Here is a sample code:

library(plotly) 

n = 10
x = 1:n
y = rnorm(n)

fig1 <- plot_ly(x = x, y = y, type = 'scatter', mode = 'lines+markers') 
fig2 <- plot_ly(x = x, y = y, type = 'scatter', mode = 'lines+markers') 
fig  <- subplot(fig1, fig2, shareX = TRUE) # shareX actually not working here
fig

Thank you in advance!
