Show main window on notification click

When an e-mail notification appears in Windows 10, I often click on it to open the e-mail immediately. It opens in a separate window. Is there a possibility to change this behaviour?

I would like to open the eM client main window instead and read the e-mail there. The reason is that I usually move the e-mail into a subfolder after reading, and this is quite uncomfortable in the separate e-mail view.

Dear developers, would you mind giving a quick reply on this?

In case anybody reads this and is interested in a solution as well: there has been opened an idea, which can be upvoted in order to make the developers consider it:
