How do I space out the grouped bar plots in plotly?

I have the following graph that I created using plotly but I would like to space the grouped bar plots (based on quarter) a little bit apart.

This is the code I used:

df = pd.melt(billed_rev['EMEA'][7:13], id_vars=['Fiscal Year/Period'],value_vars=['Val1','Val2','Val3','Val4','Val5'])
fig = go.Figure()

fig.update_layout(
    template="simple_white",
    xaxis=dict(title_text="Quarter"),
    yaxis=dict(title_text="Revenue"),
    barmode="group",
    bargap=0.2,
    bargroupgap = 0.0)

colors = ["darkgoldenrod", "darkblue","darkcyan","olive","lightblue"]

for r, c in zip(df['variable'].unique(), colors):
    plot_df = df[df['variable'] == r]
    fig.add_trace(
        go.Bar(x=[plot_df['Fiscal Year/Period'], plot_df['variable']], y=plot_df['value'], name=r, marker_color=c,text=plot_df['value'],
        textposition='outside'),
    )

fig.show()

How do I space these out?
