In this image I can increase the guide fonts alright but the fonts on the vertical guide bar (starting from 0.4) remains the same and also, is there any way to reduce the height of that guide bar too?

I’m using plotly() backend for Plots.ji in Pluto notebook

Edit 1: colorbar attributes are not reflecting anything  
`Plots.plot!(colorbar_titlefontsize=20, colorbar_tickfontsize=20)`
