Xcode 13 beta: "xcrun: error: Failed to locate 'instruments'"

Please note, I’m looking for /Applications/Xcode.app/Contents/Developer/usr/bin/instruments util (lower-case), not the Instruments app which can be found in Xcode.app/Contents/Applications.

I have both Xcode12 and Xcode13-beta-5 on my computer.
When run xcrun instruments -w <device id>, Xcode13 says xcrun: error: Failed to locate 'instruments'.

Locating the "instruments" in Xcode12:

olia@Olhas-MacBook-Pro % ls /Applications/Xcode.app/Contents/Developer/usr/bin/*instruments* 

# output ✅
/Applications/Xcode.app/Contents/Developer/usr/bin/instruments

Locating the "instruments" in Xcode13:

olia@Olhas-MacBook-Pro % ls /Applications/Xcode-beta.app/Contents/Developer/usr/bin/*instruments* 

# output ❌      
zsh: no matches found: /Applications/Xcode-beta.app/Contents/Developer/usr/bin/*instruments*

Here, Xcode-beta.app is Xcode13, and Xcode.app is Xcode12.

    There's no "instruments" util because it was deprecated in Xcode12, and in Xcode13 it seems to be removed.

    Apple recommends using xcrun xctrace instead of xcrun instruments in Xcode12. But as command xcrun instruments -w is for pre-launching Simulator, xctrace doesn't apply there.

    We can run smth like

    open -a Simulator.app --args -CurrentDeviceUDID <device id>
