Plotly to open a chart in Microsoft Edge

I am new to using plotly, and I have been able to create a Gantt chart, however, the chart does not always load in Google Chrome, but it always loads in Microsoft Edge.

Here is my code that works when I set Edge as my default browser.

import plotly.figure_factory as ff
import plotly.offline as py
df = [dict(Task="Job A", Start='2020-01-01', Finish='2020-02-28'),
      dict(Task="Job B", Start='2020-03-05', Finish='2020-04-15'),
      dict(Task="Job C", Start='2020-02-20', Finish='2020-05-30')]
fig = ff.create_gantt(df)
py.iplot(fig,filename='test')

In Chrome I get the error that the site can't be reached and the console says "Chrome not allowed to load local resource".

I have tried rendering the graph in a "pdf" but I get the following in my console.

{'application/pdf': 'JVBERi0xLjQKJd...'}

I tried rendering it in Chrome and I get this error:

Exception in Tkinter callback

webbrowser.Error: could not locate runnable browser

I am wondering what can I do to always have it open in Microsoft Edge, regardless of the default browser, and more importantly why won't it load in Chrome?
