When viewing all Sites in Salesforce, the Workspaces/Builder link will not be visible due to logged in user’s profile not added as member for the community.
If the profile is not added as a member of a community, Community Management cannot be accessed to update administration settings, including membership. This can be resolved by following the steps below:
1.Get the networkId for the community. From Setup, enter All Sites in the Quick Find box, select All Sites, and then right-click the community URL and select Inspect. The data-networkId property provides the networkId.
2.Get the profileId or permissionsetId that needs to be added. From Setup, enter Profiles in the Quick Find box, then select Profiles or Permission Sets. Click the profile or permission set that needs to be added. The ID is the last part of the URL.
3.Create a .csv file with columns for networkId and parentId. For parentId, specify the profileId or permissionsetId retrieved from Step 2. For, NetworkID, specify the networkId retrieved from Step 1.
4.Open Data Loader and select the Network Member Group object (Check the Show all Salesforce objects to view the object). Specify the location of the .csv file created and complete the Data Loader steps.
Once the profile is added as the member of the community using Data Loader, the members will be able to access Community Management from the Workspaces/Builder link on the All Sites page in Setup.
Before inserting the record into Network Member Group object using Data loader, the best practice is to turn off the Email Deliverability to avoid sending emails to the specific profile users when they are added as the member of the Community.
