Select Deploy > Show Code for Arduino, then copy the transpiled code and paste it into Arduino IDE. Judging from past discussion, this may not work since Tiny has limited data types & functions: Github for ATTiny port of XOD
Note that even if you do get it to work, any graphical programming language like XOD is going to have additional overhead, so the final program is going to require additional memory and CPU cycles, so unless you have a very simple project, XOD on a Tiny may not be a viable option anyway.
