    1. The shared mailbox needs to be set as a remote mailbox on-prem? Is it? If not provision from on-prem
      Enable-RemoteMailbox "SharedMBX" -RemoteRoutingAddress "SharedMBX@Company portal .mail.onmicrosoft.com" -alias SharedMBX
    2. Give the shared remote mailbox permissions to send to that DL from on-PREM ( I assume you syncing from on-prem to Azure with AADConnect) https://learn.microsoft.com/en-us/exchange/recipients/distribution-groups?view=exchserver-2019#delivery-management

    @Ravi Kumar Goud

    So, do you want to limit that only this shared mailbox could send emails to this group?

    Because in a hybrid environment, you could send email from Exchange online shared mailbox to local group directly without any configuration, you don't need to add shared mailbox to this list:

    Could you tell us how do you get the "access denined" issue?

    If you want to limit this group could only receive email from your Exchange online shared mailbox, you could add your Exchange online shared mailbox as mail contact on Exchange on-premises directly. Then you will could see this contact when you add mailbox to this list.
