Shared mailbox permissions

Hi Experts,

I have a client who is requesting the following

The  request is the “BC Shared Mailbox” needs to have READ ONLY Restrictions for everyone except for two users
The only ones with Read and Write access should be user A and User B everyone else should be on Read only access with no ability to delete or move emails from that inbox

Currently this BC shared mailbox has a lot of users with Full access to this mailbox

My question is

Is there are PowerShell script to modify mailbox permissions over a Shared Mailbox, remove everyone, leave User A and B, and the rest of users with only read access to the inbox
