Make bar graph with percentage

I want to put this data by vaccine type in a single bar in Plotly, showing the percentage that each vaccine represents from the total, but I am not able to do it.

import plotly.express as px

grafico_dose1 = px.bar(dose1_perc, x="percentual (%)", y=dose1_perc.index, color=dose1_perc.index)
grafico_dose1.show()
