So i have asked this question in the Flow community but haven't really got an answer so thought it was worth asking on here as it is around environment creation just using a Flow.
I am using a flow to create a number of Power Platform environments based on some data in an Excel spreadsheet. The flow loops through the Excel table and creates an environment for each row in the table. As well as creating the environment it then also creates a CDS database for the environment. This is using the PowerPlatform for Admins connectors.

It creates the environment fine. However, for all the environments it creates it sets the prefix for all custom entities and fields to craad_. Usually it is different per environment E.g. cr90b_, cr73b_ etc (With the exception of solutions where you can specify the prefix via a publisher).

I cant see any parameters you can specify in the connector to set the prefix so wondering if anyone else has had this issue?
I am also wondering if i am missing some further steps in the flow that i should be doing when setting an environment up? Nothing is shouting out to me so any help is appreciated. Permissions will be setup separately on the environment but if there are any other actions people recommend when setting up environments via flow i am interested to understand what they are.
Thanks
