Dear Filip Zdravkoski,
Good day!!
Apologies for the inconvenience caused and please don’t worry, let’s work together on your concern and move towards a resolution path.
I understand your concern and to my knowledge, Microsoft provides Microsoft 365 Developer program for the test purposes to the developers who can test the scenarios and deploy to their production environment.
However, since you mentioned you are not able to use Microsoft 365 Developer Program because they try to add a new verification process, you can connect with the related development team at the Microsoft, where they will try to help you with skipping the verification process and give an alternative to your requirement.
Moreover, you can also subscribe the trail versions of Microsoft 365 subscriptions and see whether it can help you.
In addition, I will keep this thread open so that MVPs and experts in this community can share their ideas on this concern.
Appreciate your patience and understanding. Have a great day!!
Best Regards,
Sophia
