How to fetch M365 group members via pnp graph in SPFX

Question

I'm trying to list out all the members of a M365 group connected to a team site via a SPFX webpart.
Steps-

1. get the Group id of the current team site.
2. Using the group id, fetch the members of the group.

I don't see any function to list out the members of the group like (graph.groups.getById(groupId).Members??)

Here is the code snippet-

import { graph } from '@pnp/graph'  
import '@pnp/graph/Users' 
import '@pnp/graph/groups' 
//to get the group ID
 graph.groups.top(999).select('mailNickname,id').get().then(groups=>{

      groups.forEach(group=>{

        if(group['mailNickname']==currentSiteAlias)
        {
//set group ID
          groupId=group['id'];
//get the members
          graph.groups.getById(groupId).Members.then(memberObject=>{
            console.log(JSON.stringify(memberObject))
          }

          );

        }
      })
    }).catch((err) => {  
      console.log("Error fetching Group ID "+err)})

Hi @Kevin Thankachan ,

Use expand() like this:

 graph.groups.getById(groupId).expand("members")()  

Here is the full code snippet, please refere:

  private GetGroupMembers()  
  {  
    graph.groups.top(999).select('mailNickname,id').get().then(groups=>{  
      console.log(groups);  
      groups.forEach( group=>{  
  
        if(group['mailNickname']== "NewProvision")  
        {  
           let groupId = group['id'];  
           const groupMembers =  graph.groups.getById(groupId).expand("members")().then(group=>{  
            console.log(group.members);  
          });  
  
        }  
      })  
    }).catch((err) => {  
      console.log("Error fetching Group ID "+err)});  
  
  }
