How to show nearby BLE devices via web withour prompting the user for coupling?

I'm currently trying to implement a way of discovering nearby ble-devices and reading their signal strength via web. I already found bluetooth-request-device-functionality. Unfortunately, this prompts the user to connect to a nearby bluetooth device.

I want to present nearby ble devices in a custom style css, without actually pairing to a device. Is there any way of just reading the advertisments without needing to pair to a device?

I hope, you can help me.
