Sending a gmail message - python-3.x

Question

im trying to send a gmail message with the following code:
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
import base64
def create_message(sender, to, subject, message_text):
"""Create a message for an email.
Args:
sender: Email address of the sender.
to: Email address of the receiver.
subject: The subject of the email message.
message_text: The text of the email message.
Returns:
An object containing a base64url encoded email object.
"""
message = MIMEText(message_text)
message['to'] = to
message['from'] = sender
message['subject'] = subject
#return {'raw': base64.urlsafe_b64encode(message.as_string())}
b64_bytes = base64.urlsafe_b64encode(message.as_bytes())
b64_string = b64_bytes.decode()
#body = {'raw': b64_string}
return {'raw': b64_string}
s = "email"
t = "email"
sub = "test subject"
m = "message test"
create_message(s,t,sub,m)
where s = my email(replaced with "email" in this example and t = my other email (again replaced))
It doesnt kick out any errors but doesnt send the message.
Also this code didnt work:
#return {'raw': base64.urlsafe_b64encode(message.as_string())}
as it produced the following error: TypeError: a bytes-like object is required, not 'str'
"I solved that" with this:
b64_bytes = base64.urlsafe_b64encode(message.as_bytes())
b64_string = b64_bytes.decode()
#body = {'raw': b64_string}
return {'raw': b64_string}
edit(1): I do have credentials.json and passed the google api example

Needed to create client_secret.json and paste my credentials there, ctrc+c, ctrl+v an old example and update it to python 3.x, resolved base 64 issue and it works :)
