I want to filter the data that appears in the ResumeCart screen by the user who suspended the transaction so that the user only shows his transactions.
I found a filter function and expected it would do the job and wrote the following code.

import * as ResumeCart from "PosApi/Extend/Views/ResumeCartView";
import { IExtensionCommandContext } from "PosApi/Extend/Views/AppBarCommands";
import { ObjectExtensions } from "PosApi/TypeExtensions";
import { GetLoggedOnEmployeeClientRequest, GetLoggedOnEmployeeClientResponse } from "PosApi/Consume/Employees";
export default class ResumeCartFilterByUser extends ResumeCart.ResumeCartExtensionCommandBase {
    private _state: ResumeCart.IResumeCartExtensionCommandState;
    private _isFiltered: boolean = false;

    constructor(context: IExtensionCommandContext<ResumeCart.IResumeCartToExtensionCommandMessageTypeMap>) {
        super(context);

        this.id = "LogicFilterByUser";
        this.label = "Filter By User";
        this.extraClass = "iconLightningBolt";
    }

    protected init(state: ResumeCart.IResumeCartExtensionCommandState): void {
        this._state = state;
        this.isVisible = true;
        this.canExecute = true;
    }

    protected async execute(): Promise<void> {
        this._isFiltered=!this._isFiltered;
        if (this._isFiltered) {
            const employeeResponse =
             await this.context.runtime.executeAsync(new GetLoggedOnEmployeeClientRequest<GetLoggedOnEmployeeClientResponse>());
            if (!ObjectExtensions.isNullOrUndefined(employeeResponse) && !employeeResponse.canceled  )
            {
             const employeeId = employeeResponse.data.result.StaffId;
              this._state.suspendedCarts.filter(cart => cart.suspendedCart.Cart.StaffId === employeeId);
            }
            else
            {
                this._isFiltered = false;
            }
        } 
    }
}

But when the order is executed, there are no changes to the records displayed
I know that I may be using the function incorrectly, but I searched and did not find any example of filtering data, I hope you give me an example of filtering data or correct the code to work and filter the data
