SSRS unable to send email subscription notification using SendGrid from a VM/AZURE

Question

In SSRS (using a VM in AZURE) I configured eMail  to use SendGrid.
When the subscription triggered I get the following error:
Failure sending mail: Mailbox unavailable. The server response was: Cannot receive from specified address <[email protected]>: Unauthenticated senders not allowed
I talked to SendGrid support and they say that you need to be authenticated (They provided a username and password when I registered) but I can't find the way to provide the credentials. I tried to insert them in the rsreportserver.config file but if I change
SMTPAuthenticate to 1, to use the credentials, the email option doesn't show in the subscription setting form in SSRS (See below).

                    </RSEmailDPConfiguration>
                </Configuration>
Is there any other SMTP that I can use in a AZURE VM that will send email just using a valid email (I can do that in my internal SMTP)?
Is there a way to provide the credentials?
Thanks in advance!

Hi SendGrid,
According to your description, you want to use the SendGrid SMTP server for configuring email subscription. Now you have the problem on sending the credential to access the SendGrid SMTP server. Right?
In Reporting Services, when configuring subscription, we need to specify a Windows domain user to run the Reporting Services. Definitely this domain user credential can't access the SendGrid SMTP server. In this scenario, we need to install the Local
SMTP server and configure the SMTP virtual server. And we can put credential in Access Control. For detail steps, please refer to similar threads below:
