I am unable to switch my profile and that option is not being shown.
you try to check which license is assigned to your account?
If it is Automation express or Citizen developer is assigned try to change it to Automation Developer.

You should have Automation Developer License allocated to your Studio user account.

Most likely you are on the FREE license tier. Only StudioX is available. Make sure you use a community version or that you have proper entitlements in enterprise.
