How to use the @azure/core-amqp.Constants.attachEpoch function in @azure/core-amqp

source: {
        address: this.address
      },
      credit_window: 0,
      onMessage: options.onMessage || ((context: EventContext) => this._onAmqpMessage(context)),
      onError: options.onError || ((context: EventContext) => this._onAmqpError(context)),
      onClose: options.onClose || ((context: EventContext) => this._onAmqpClose(context)),
      onSessionError:
        options.onSessionError || ((context: EventContext) => this._onAmqpSessionError(context)),
      onSessionClose:
        options.onSessionClose || ((context: EventContext) => this._onAmqpSessionClose(context))
    };

    if (typeof this.ownerLevel === "number") {
      rcvrOptions.properties = {
        [Constants.attachEpoch]: types.wrap_long(this.ownerLevel)
      };
    }

    if (this.options.trackLastEnqueuedEventProperties) {
      rcvrOptions.desired_capabilities = Constants.enableReceiverRuntimeMetricName;
    }

    const eventPosition = options.eventPosition || this.eventPosition;
    if (eventPosition) {
      // Set filter on the receiver if event position is specified.
      const filterClause = getEventPositionFilter(eventPosition);
      if (filterClause) {
        (rcvrOptions.source as any).filter = {
          "apache.org:selector-filter:string": types.wrap_described(filterClause, 0x468c00000004)
        };
      }
