Your problem
My problem is:

Unable to connect to my regular gmail account (the free version).

Details -
I am very very new to Mautic and as such I wanted to test Mautic before going live with this.

Here is what I have done thus far -

1. Uploaded and installed Mautic on my test server.
2. I was trying to add my regular gmail here - Configuration → Mail Send Settings → E-mail address to send mail from
   As I cannot upload any image here, here are the settings on this box -

Custom return path (bounce) address: the same email address
Mailer is owner - Yes
Service to send mail through - Gmail
Username for the selected mail service - the email address
Password for the selected mail service - the gmail password

I have then clicked the save button. And it seems to persist (which confirms that the details are saved).

Now when I click the “Test Connection” button or the “Send Test Mail” - I get the following error -

Failed to authenticate on SMTP server with username “my-actual-email@gmail.com” using 1 possible authenticators. Authenticator LOGIN returned Expected response code 235 but got code “535”, with message "535-5.7.8 Username and Password not accepted. Learn more at 535 5.7.8 https://support.google.com/mail/?p=BadCredentials a22sm14264193wrc.59 - gsmtp

Would be thankful if you could help me resolve this issue.

In gmail setting you must enable Less Secure Apps

Thank you for the reply. But sadly, this does not seen to resolve the issue and I still get the same error.

Are there some more steps involved?

It might be worth mentioning that as of now, I have not setup the Cron Jobs or even the IP Lookup. I kept them on hold as I was eager to get the email setup first.
