Hi Jesus Soto Urbiola,
You can edit the grid by using its default class name
.mx-datagrid. Using the following code u can select the row and the set a button on top to trigger a microflow where all the form object can be duplicated and created on a new row as a new object..
You can make a datagrid editable trough an option in the individual collumns properties. Do note that the users needs to have the proper write access.
