How to plot p values using plot_sensors_connectivity

Hi, I want to investigate the changes of brain connectivities, however, the function mne.viz.plot_sensors_connectivity could show only 20 strongest connections. How could I plot the changes or significance p values, like connections of 0~0.05?
I tried to alter threshold:
ii, jj = np.where(con >= threshold)
ii, jj = np.where(con <= 0.05)
but I don’t know how to change the colorbar’s numerical labels and the color type (like white for >0.05 and red for 0)
I hope more params can be provided in the next version, such as the number of connectivities, order, the color map of the bar…
Thank you.
