Want to delete a Tenant - Mission Imposible

Question

I just want to delete a tenant that is not being used and appears as a guest in my personal teams account.
I have followed all the steps, but it seems that its impossible to delete,
1.- In Microsoft Entra Admin Center

2.- I followed this advise ->

But,

3.- I tried to manage access to all Azure subscriptions and management groups in this tenant

It's impossible to select the "Yes" Option as the save button is disabled.

4.- I tried to get those permissions through Azure, nowhere to find.

Can somebody in the name of god help to accomplish this very simple task

Perhaps I don't fully understand your question, but do you mean you would like to have full access to all subscriptions? This can be done when you have the Global Admin role and you check this box: https://learn.microsoft.com/en-us/azure/role-based-access-control/elevate-access-global-admin
