@bbanic23 configure your flow as follows:
Configure the Get Emails action as follows, you can apply more settings, like select specific folder, change Top count - count of emails to be returned by this action, apply filters like from, to, etc. I would suggest to apply more filters to narrow down the number of emails to be returned by this action

Then loop through value (items from Get Emails) using Apply to each action, then again loop through attachments of email inside the Apply to each using Apply to each again, see below screenshot for reference, then get the attachment and save it to onedrive.
