1. **Access Messaging Flows**: 
   * Click on '''WhatsApp''' in the left menu.
   * Select '''Messaging Flows'''.

2. **Edit or Create a New Flow**:
   * If you want to edit an existing flow:
     * Choose the flow you wish to update.
     * Click on '''Update'''.
     * In the flow builder, click a node (+) where you want to insert the step, triggering a modal window to appear.
   * If creating a new flow:
     * This automatically opens a modal window in the Flow builder.

3. **Add the Contact Update Step**:
   * In the modal, locate and click on the '''Contact Update''' option.
   * After selecting it, click the '''Add''' button.

4. **Configure the Step**:
   * In the new modal that appears:
     * Click the '''pencil icon''' to give your step a name. Choosing a unique, short name is recommended for clarity.
     * Under the '''Default''' tab, select the field you wish to update.
     * You can now either type a value directly into the field or click the '''lightning bolt''' icon to select a variable.
     * For custom fields, switch to the '''Custom''' tab and click the '''Add property''' button. From here, select the custom field that you want to update via the first dropdown menu.

Depending on the selected field type (whether text or selection fields), you will either directly input a value, select a value from a predefined list, or choose an option using the dropdown provided.
