I don't use Google cloud but the seven step OIDC configuration process is the kind of thing that can be scripted quite easily in Azure, e.g. using the az CLI tool. When a step creates a new object the command can return its ID so you can save it in a variable and use it in a subsequent step. If Google has something similar this seems preferable to the alternatives.
