I was a happy user of Harmony IR all-in-one remotes for many years, but alas some time after the takeover by Logitech they gave warning that they would end their IR remote control product line. Open source projects like Concordance and Congruity that had popped up soon died off.
I implored Harmony/Logitech many times over to open source their vast database of IR codes, or at least make it available. Now it seems to have been squandered, meaning that a project like this OP one has to use a learning-mode per device and cannot select from almost every known consumer electronic IR code that Harmony enjoyed. Does such a publicly available database exist? Many cheap all-in-one IR remote controls came with printed tables of numeric codes, but those were not the actual IR codes themselves and were not universally applied across brands.
Nowadays a Sofa Baton (IR & Bluetooth) remote does the job.
The last device I pulled was a TCL 75Q77K which might have been released around March 2025 which was 2 months before Logitech announced the discontinuation of Logitech Harmony Remote Software so they might be done adding new devices. I dunno.
