Role to schedule updates

[pluc7]

Hi guys!
My client has created an automation account and I should manage automatic updates through scheduling.
He assigned me the role of Automation Operator but I can't see the Schedule update deployement entry in the Update management tab .
I tried with the role of Automation Job Operator but nothing.
What role is needed to be able to create a schedule for updates? Do I have to have a role for subscription?

Thanks!

My client created a custom RBAC role and entered the two permissions:

- Microsoft.compute/virtualMachines/write
- Microsoft.OperationalInsights/workspaces/analytics/query/action

I can't see the Schedule update deployment entry in the Update management tab . Why??? I have these permissions:

This automation account is linked to the subscription and I I don't have a role on this subscription, could this be the reason?
