Adding custom column to a Sharepoint library using Graph API

I want to be able to add a custom column to a Sharepoint library using Graph API. I was able to create the library using article https://docs.microsoft.com/en-us/graph/api/list-create?view=graph-rest-1.0&tabs=http but I don’t find any information on adding custom column after the library is created. I tried to do PUT and PATCH operation but it throws 400 Bad Request. I also checked below article https://docs.microsoft.com/en-us/graph/api/listitem-update?view=graph-rest-1.0&tabs=http but it doesn’t tell any way to adding a custom column
