Feature request: a software to record the cumulative time of use of a software

As PLAY TIME on Steam.

I’m on Arch Linux KDE on PC.

I found:

e.g.

time supertuxkart
...
real    1m13.823s
user    0m6.734s
sys     0m3.023s

but not cumulative, I not wanna make additions…

Also:
activitywatch$net
aur.archlinux$org/packages/activitywatch-bin
but it not works for me aur.archlinux$org/packages/activitywatch-bin#comment-1033021 & I only want the cumulative use time of use of a software, I’m not interested of timeline etc.

About Non-Steam games play time, e.g. a Non-Steam .exe on Proton
github$com/ValveSoftware/steam-for-linux/issues/11867
sound of cicada

So a KDE software, a window where we can select a software (its executable), it records the time of use, it displays its time of use.
