Access Picker dialog seleniun sugem in Google (Python)

Question

Hello I’m a beginner in programming, and I couldn’t find an explanation of how to solve my problem by searching the net. I am trying to access a spreadsheet file that is in my GDRIVE, through MY MAPS:

# coding=utf-8
from selenium import webdriver
from time import sleep

navegador = webdriver.Chrome()
#Acessar no MyMaps Google
navegador.get("https://www.google.com/intl/pt-BR/maps/about/mymaps/")
navegador.find_element_by_xpath('/html/body/div[3]/div/div/p[2]/a').click()
# Logar na conta
navegador.find_element_by_xpath('//*[@id="identifierId"]').send_keys('xxxxxxxxxxxxxxxxxxxxxxxxxxxx')
navegador.find_element_by_xpath('//*[@id="identifierNext"]/div/button/span').click()
sleep(3)
navegador.find_element_by_xpath('//*[@id="password"]/div[1]/div/div[1]/input').send_keys('xxxxxxxxxxxxxx')
navegador.find_element_by_xpath('//*[@id="passwordNext"]/div/button/span').click()
sleep(3)
# Entrar no mapa
navegador.find_element_by_xpath('//*[@id="docs-editor"]/div[2]/div[2]/div[2]/div/div[3]/div[2]/div[1]/div').click()
sleep(3)
# Carregar a planilha
navegador.find_element_by_xpath('//*[@id="ly0-layerview-import-link"]').click()
sleep(5)
#apertar google drive
navegador.find_element_by_xpath('//*[@id=":7"]/div').click()

But when I implement the attempt to click to access the Gdrive, in the dialog Picker that appears, returns me this error:

Traceback (most recent call last):
  File "D:/Curso de Python/Jhony2/Automacao_seleniun.py", line 18, in <module>

I imagine I have to enter the Picker dialog, in order to manipulate what is inside it. Someone could help me implement this?
