Is there an app/command that allows me to view recent notifications?
Preferably text-based.
I would also like to view the notification timeout for each notification. ;)

There isn't any command for retrieving previously send messages in Desktop Notifications Specification so my guess is that they are discarded after retrieving.
You can however observe these using dbus-monitor command, like this:
$ dbus-monitor "interface='org.freedesktop.Notifications'"
Sending simple notification:
$ notify-send "Hi there!"
results with following information:
method call time=1555095758.597788 sender=:1.385 -> destination=:1.386 serial=6 path=/org/freedesktop/Notifications; interface=org.freedesktop.Notifications; member=GetServerInformation
method call time=1555095758.601101 sender=:1.385 -> destination=:1.386 serial=7 path=/org/freedesktop/Notifications; interface=org.freedesktop.Notifications; member=Notify
string "notify-send"
uint32 0
string ""
string "Hi there!"
string ""
array [
]
array [
dict entry(
string "urgency"
variant byte 1
)
]
int32 -1
signal time=1555095765.734845 sender=:1.386 -> destination=:1.385 serial=15 path=/org/freedesktop/Notifications; interface=org.freedesktop.Notifications; member=NotificationClosed
uint32 1
uint32 1
Time field is an UNIX timestamp, can be translated like this:
$ date -d @1555095765
Fri Apr 12 21:02:45 CEST 2019

This is so annoying... I get notifications from things like the power/battery on my lock screen but it doesn't tell me what they are, and they disappear before I can log in to see what they are! – Michael May 6 '20 at 5:50
I've been using this for over a year on UbuntuMate 16/18
