The sad thing about the current state of macOS is that I'd rather install an app to manage the menu bar than upgrade to the liquid glass monstrosity that is macOS Tahoe.
(I'm also not an early adopter. I only went to Sequoia from Ventura a few months ago.)
in case this implies you haven't found it: it's a feature in Sequoia :) it's just in display settings, though you may have to turn on the "show all resolutions" toggle to show it.
I haven't used Tahoe personally for more than a moment on someone else's computer, but wow they did not think that UI redesign through at all, did they. I'm actually kinda glad I'm mac-less now.
