Adding and Deleting LSHandlerURLScheme from com.apple.launchservices.secure.plist is not immediately reflecting in Launch Services database

I am exposing an Mac OSX application by adding its bundle identifier and urlscheme in com.apple.launchservices.secure.plist.

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<key>LSHandlerPreferredVersions</key>

<dict>

<key>LSHandlerRoleAll</key>

<string>-</string>

</dict>

<key>LSHandlerRoleAll</key>

<string>com.test.myurl</string>

<key>LSHandlerURLScheme</key>

<string>myurl</string>

</dict>

</plist>

Until I restart the machine I don't see the url scheme in lsregister - dump output

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -dump | grep myurl

canonical id: com.test.myurl (0x80000008)

URL scheme: myurl

all roles: com.test.myurl (0x80000008)

Even immediately after deleting these entries from the plist is also not reflecting in lsregister , I need to restart.

I tried Kill, seed of lsregister but no luck. How to update this entries in lsregister without a restart
