I want to check the sending history of approval request emails

Content (please ensure you mask any confidential information):

I have the following questions.

I am using the standard approval request email feature, but I have received reports that emails are not being received.

Upon checking, we have found that the emails have been received for other orders, and there are no problems with those.
Therefore, we believe there is some kind of problem with a very small number of emails, and we are currently investigating the issue.

So, I would like to check the system history to see if approval request emails have been sent. Is this possible?

Thank you.
