Can iOS Simulator from macos GitHub action runner be used for Appium?

I have an iOS app with end2end test written with webdriverio running on appium.

I want to run this within GitHub action. Most of the job failed despite I keep increasing the waiting time and retry interval and duration.

Among all my test (hundreds, only one was able to get to the emulator started and executing tests)

I reported the issue here:

If I host myself the github runner for macOS, it perform fine.

Apparently, it is possible to increase the performance of the runner using github action corporate:

I will have to ask the CTO of our organisation, is this the only way to let github action run those tests on the cloud?
