Anybody have idea how to add/update "Custom Layout Update" field of category or product in magento version 2.3.4
According to magento standard document,"You can no longer specify an entity-specific layout update with text but instead must create a physical file that contains the layout updates and select it for use."
But there is no option to select physical file on categories or product edit level.
After upgrade version from 2.3.3 to 2.3.4, which categories have "Custom Layout Update" exist now those are with drop down and "Use existing" selected but which does not have custom layout update those are with "No update" on drop down.
so really confused that how we could add new or update existing?
