How do you get access to Co Pilot studio?

Question

Hi All, I am trying to access Co Pilot Studio, mainly just to test out its capabilities to see if it is capable of what I require. However;

I cannot login with a personal email account.

I have a work based email but it says 'We can't finish signing you up because Microsoft Copilot Studio isn't currently available for your work or school account associated with (insert my email)'. I am not sure why this is the case.

I have been looking into the issue and have found a help page which says you can sign up for the Microsoft 365 Developer Program, which provides a free work account that you can use to access Copilot Studio. I have done this but cannot find anywhere in the Developer Program login that allows me to do this.

Can anyone advise me how I can obtain access? I dont mind if this is through my work email or through the Developer Program.

Thanks in advance.
