Possibility of a Web App to act as a Bluetooth Low Energy Beacon for BLE advertising?

I've been taking a look into the documents from https://googlechrome.github.io/samples/web-bluetooth/ and it seems nearly all of the samples demos or codes is mostly the web app acting as a central. I'm looking to know if there's a possible way to utilize the codes in someway to make my web app to be a peripheral or if.... there's a peripharel simulator out there based as a webapp. The closest i found is based as an android app.

I'm looking at the possibility to actually implement it into a PWA.

Thanks a bunch for taking the time to read!
