Cannot create private channel as part of a new team payload

[sarjumulmi]

When I try to create a new team along with a new private channel, the channel is hidden & set to a standard membership type.

        reqBody := graphmodels.NewTeam()
	displayName := "My Test Team"
	description := "My very first test team"
	reqBody.SetDisplayName(&displayName)
	reqBody.SetDescription(&description)

	conversationMember := graphmodels.NewAadUserConversationMember()
	roles := []string{
		"owner",
	}
	conversationMember.SetRoles(roles)
	memberAdditionalData := map[string]interface{}{
		"[email protected]": fmt.Sprintf("https://graph.microsoft.com/v1.0/users('%s')", ownerID),
	}
	conversationMember.SetAdditionalData(memberAdditionalData)

	members := []graphmodels.ConversationMemberable{
		conversationMember,
	}
	reqBody.SetMembers(members)

	channel := graphmodels.NewChannel()
	channelDisplayName := "test pvt channel"
	channelDescription := "test pvt channel for test team"
	membershipType := graphmodels.PRIVATE_CHANNELMEMBERSHIPTYPE //setting membership type to private 
	channel.SetDisplayName(&channelDisplayName)
	channel.SetDescription(&channelDescription)
	channel.SetMembershipType(&membershipType)
	channel.SetMembers(members)
	channels := []graphmodels.Channelable{channel}
	reqBody.SetChannels(channels)

	templAdditionalData := map[string]interface{}{
		"[email protected]": "https://graph.microsoft.com/v1.0/teamsTemplates('standard')",
	}
	reqBody.SetAdditionalData(templAdditionalData)

	team, err := gc.Teams().Post(ctx, reqBody, nil)
	if err != nil {
		log.Panicf("error creating team: %v", err)
		return
	}

When I query for the channels in the new team created, it comes back as standard. I can see the new channel under Hidden Channels in the UI & it's set to a standard channel.

        channelsResp, err := gc.Teams().ByTeamId(teamID).Channels().Get(ctx, nil)
	if err != nil {
		log.Panicf("error creating channels: %v", err)
		return
	}

	for _, ch := range channelsResp.GetValue() {
		log.Printf("channel: %s: %s\n", *ch.GetDisplayName(), ch.GetMembershipType())
	}
       // logs:
       // channel: General: standard
      // channel: test pvt channel: standard

Expected Behavior:
Channel is shown & membership type is set to private
SDK version:
v1.43.0
