I am wondering if there is a way to see all possible arguments for a function. For example, EntityValue can accept "NonMissingEntityAssociation" and "NonMissingPropertyAssociation" but these will not autocomplete so the only way I learned about these was by watching a Wolfram University course. Another example is VertexShape function does not autocomplete all of the possible options. I would then like to add autocompletion for all the acceptable strings for options if there is a way to get this data.
