Potential Sell Swing on GBP/USD

currently observing a potential swing trade setup for a sell on GBP/USD. The price is approaching a previous support level aligned with supply zone as strong keylevel point as marked on the 1-hour chart.

will wait for confirmation on the 5-15 minute charts.
The confirmation will be a change in market direction from bullish to bearish.
Once I observe a bearish reversal, I will consider entering a sell position.If nothing happen, will expect price can go more up for the next supply zone
