how to enlarge title bar icons? (minimize, maximize, close) - SOLVED

I recently upgraded my monitor to 3440x1440 and learned out to tweak numerous settings to match the new desktop. There's one item I haven't been able to resolve: how to enlarge the title bar icons for Thunar and other built-in apps, though not for lack a trying. I think changes to the Thunar title bar should also apply to text editor (xed), Update Manager, Libre Office apps, and Xfce settings apps, as all these appear to have the same title bar. In any case, I would be thrilled to fix Thunar as I interact with it waay more than any other app.

I came across this discussion with posts by @ToZ that may provide the answer, except I don't know how to determine if I'm dealing with SSD's or CSD's (new terms for me). I already tried the css code referenced in that discussion but no joy. Rather than post my question in a 3-year old thread, I thought it best to start my own. Assistance would be greatly appreciated!

BTW, I'm running Mint 22.2 with Xfce 4.18.4 and Mint-L-Dark-Brown style.

Added later 22 h 27 min 42 s:
Additional info... I just verified that the css code referenced in above-linked discussion impacts the title bar for apps such as Disks and Software Manger. I gather from comments in that discussion that those apps are server side decorated (SSD). At least now I know how to adjust those, but the apps I most often use are apparently CSD.

Prior to upgrading to LM22, I was able to get larger title bar buttons in Thunar, Text Editor and other built-in apps by using the Default-hdpi theme. I didn't see this theme when I upgraded to LM22 a few months ago. I just realized there are TWO places to set themes in Xfce -- from Appearances and from Window Manager. I previously only checked Appearances. I just found the Default-hdpi theme in the Window Manager themes list. That fixed my title bar icons, without having go deeper!
