Is there a way to see/display notifications' history on Ubuntu 18.04?

EDIT:
I installed indicator-notifications following this answer but, contrary to what was told in the answer,

You will find a little mailbox in the panel:

there was no icon of the tool appearing on my top-bar after I rebooted my PC.
Also, I tested the tool using : notify-send 'test message', I got a normal notification as I used to get before installing the tool, but my question is about viewing the history of notifications (like in a log file or something like that), which I didn't get using this tool (may be I miss-used it).

Update [Aug 28 2019]: Recently, I noticed that web notifications "as native" are working but disappearing without being consumed. If I'm fast enough to click them while appearing, they send me to the correct tab/webapp. If a few seconds pass, without doing anything,the notification disappears.

Original question:

I'm trying to make chrome notification show as native notifications on Ubuntu 18.04 (which UI is based on Gnome).

I tried enabling enable-native-notifications, but it didn't work. See screencap below.

I tried searching Q&Aa like this and this, but they discusses old versions of Ubuntu.

Any idea how to make chrome notifications appear as native ones on Ubuntu 18.04? Thanks.

* BTW, I understand that there's a bit of a problem regarding synchronization between browser apps vs. native functionality, meaning, had this feature worked, if I would have consumed a message on the browser's app, would it disappear from the native notifications panel?

I'm using Ubuntu 12.04 with two hard drives.

The second drive is set to mount to /home/myuser/DATA and it mounts OK. However gnome shows a 'Removable Devices' item in notification area which lists my hard drive with the unmount button.

How do I make Ubuntu to treat the second hdd like the system one, without suggesting me to unmount it in the notification area?

After installing Ubuntu 12.04, I have a problem with Banshee: it doesn't have a tray icon. I know about the tray-icon-plugin, but it's not working:

I'm using Gnome 3 in classic mode. In gnome-shell Banshee has an icon. How can I get the tray-icon to work in a classic session?

I was wondering if there was a simple way to close Teamviewer to the notification area like I would close Skype?

EDIT:

Just to clarify my initial post, I want to enable Teamviewer in the notification area so that I can close it in my open programs bar (click on x), and it would still be running in the notification area (Skype does that, I can option Banshee and Rhythmbox to do that, and Transmission does this too). All Tray puts it into the notification area, but the x still closes Teamviewer completely, and I have not found an optional setting in Teamviewer either.

Thanks for the answer though Karni! ;)
