How to add separate lines to mplfinance plot?

Question

TL;DR

Is there any way to add separate lines to an mplfinance plot, like the image below, to show how a trade went? I know how to add points, but I can't figure out how to add separate lines.

Replication

Say you have a pandas dataframe that looks like this:

Date	Open	High	Low	Close
20190608	9586.35	9586	9586	9586.35
20190609	9586.35	9586	9586	9586.35
20190610	9586.35	9586	9586	9586.35
20190611	9586.35	9586	9586	9586.35
20190612	9586.35	9586	9586	9586.35
20190701	9595.94	9873	9596	9674.55
20190702	9588.27	9692	9556	9576.77

Using mplfinance it's possible to plot and save an OHLC chart with something like this where df is the said dataframe:

import mplfinance as mpf

# plot
fig, axlist = mpf.plot(
    df, type="candle", style='yahoo', ylabel='',
    xrotation=30, returnfig=True, figsize=(6,4))
# save
fig.savefig(filename, bbox_inches='tight',
    pad_inches=0.1, dpi=96, transparent='True')

Additional lines include a vertical line, a horizontal line, a line connecting two or more pairs of dates and prices, and a trend line. Here is an example of simply drawing a line with date and price. Please refer to this page for more details.

import datetime
import pandas as pd
import pandas_datareader.data as web
import mplfinance as mpf

import yfinance as yf
data = yf.download("AAPL", start="2021-01-01", end="2021-07-01")

two_points = [('2021-06-04', 128),('2021-06-30', 138)]
mpf.plot(data, figratio=(8,4), type='candle', alines=two_points, volume=True, mav=(5, 25), style='yahoo')
