Missing Support for Arduino Uno R4 WIFI

[kjudd42]

When compiling for an Arduino Uno R4 WIFI, Arduino IDE 2.3.4 on Windows 10, #include throws the following error:

WARNING: library TimerOne claims to run on avr, esp32 architecture(s) and may be incompatible with your current board which runs on renesas_uno architecture(s).
C:\Users\kjudd\OneDrive\Documents\Arduino\Multifunc_Sheild_Beeper\Multifunc_Sheild_Beeper.ino: In function 'void setup()':
C:\Users\kjudd\OneDrive\Documents\Arduino\Multifunc_Sheild_Beeper\Multifunc_Sheild_Beeper.ino:8:8: error: 'class TimerOne' has no member named 'initialize'
Timer1.initialize();
^~~~~~~~~~

Works fine on 2 'HERO' boards from inventr.io, can only include its just missing the support for the new architecture in the R4. Tried it with both inventr.io's included v 1.1.1 and the latest v 1.2 from GitHub, same error.
