Using personal/multiple credentials to each connection

We are an MSP connecting to different customers machines with RDM.

Sometimes we're required to use personal credentials for each admin agent for the connection to our customers.
How can I create an RDP Entry in RDM and when I connect to the machine it will use my credentials to that customer, but when my colleague connects it will use his credentials instead?

We're using Keeper Password Manager to store our credentials and we want to connect each admins personal entry in Keeper to the same RDP connection.

We're connecting to the data source with personal Entra ID credentials.
