Drupal noob here.
Problem: Unable to reuse blocks created using Bootstrap Layouts module; being forced to manually re-enter data in order to duplicate a block in a new locaion.
Details and any research: Custom blocks seem to be made for reusability, but I'm struggling to find and insert any of the previously created blocks into new pages using the layout builder
Tried: searched Stack, Drupal forums and Google for "unable to reuse drupal custom blocks" and similar queries; read through what I understand of the Drupal and Bootstrap Layouts documentation.
Attached image shows an example of a custom grid block ("What We Do") which I'd like to be able to insert on a different page; unable to find it in any kind of list/library when in the target page layout builder. Forced to recreate it from scratch. Surely there's a way!
