SolarEdge integration - how to get the chargelevel?

Hi!
Today my photovoltaic system has been put into operation. Of course I want to display the data in the HomeAssistant. I am using the SolarEdge integration via the API to do this.
Unfortunately, the battery charge level is not displayed as a sensor.
When I call the API in the browser, the level is displayed (STORAGE --> chargeLevel):

"siteCurrentPowerFlow:{“updateRefreshRate”:3, “unit”: “kW”, “connections”:[{“from”: “GRID”, “to”: “Load”},{“from”: “STORAGE”, “to”: “Load”}], “GRID”:{“status”: “Active”, “currentPower”:0. 04}, “LOAD”:{“status”: “Active”, “currentPower”:0.37}, “PV”:{“status”: “Idle”, “currentPower”:0.0}, “STORAGE”:{“status”: “Discharging”, “currentPower”:0.33, “chargeLevel”:82, “critical”:false}}}

How do I solve this?
Thanks a lot!
