Unable to see my Organisation when creating a new submission

I am trying to create initial submission on behalf of my organization. My organization is registered with EMA. But when I am trying to create a submission on behalf of my organization, that organization name does not appear on IRIS portal. So I am not able to proceed further.
How I can add my EMA registered organization in my IRIS account? Please guide me.
 

For specific technical issues with IRIS or SPOR-OMS, please create a ticket in the EMA Servicedesk system. Note that an organisation must be listed in the OMS system of SPOR, to be visible in IRIS. Organisations should be added, modified or deleted directly in OMS, not in IRIS.

To be able to create submissions on behalf of an organisation, an IRIS user must be affiliated to that organisation, with the role of IRIS Industry Manager; the affiliation request must be done in the EMA account management system. We note that your IRIS user account is not affiliated to any organisation.
