Thank you everyone!. I was applied solution explained in
about modifying the comments in private/IRTimer.cpp.h and working as I need and not interfiering with other libs.
Of course, big comment in this ---> "The modification must be renewed for each new IRremote library version, or you use an IDE like [Sloeber. For other platforms you must modify the approriate section guarded by e.g. #elif defined(ESP32)"
but works for me.
Again, cheers everyone.
