Opening custom extension's URL with a non-default web browser

Thanks Nick,

Since I can’t make it work, please correct these two extensions:

# popclip
name: GCTS Library
icon: square filled GC
javascript: |
  const term = encodeURIComponent(popclip.input.text)
  const url = `https://gordonconwell.on.worldcat.org/v2/search?queryString=${term}&clusterResults=on&stickyFacetsChecked=on&baseScope=sz%3A36213`
  popclip.openUrl(url, {app: 'com.google.Chrome'})

# popclip
name: TIU Library
icon: square filled TIU
javascript: |
  const term = encodeURIComponent(popclip.input.text)
  const url = `https://i-share-tiu.primo.exlibrisgroup.com/discovery/search?institution=01CARLI_TIU&vid=01CARLI_TIU:CARLI_TIU&tab=LibraryCatalog&search_scope=MyInstitution&mode=Basic&displayMode=full&bulkSize=10&highlight=true&dum=true&query=any,contains,${term}&displayField=all&scopeSelecter=LibraryCatalog&pcAvailabiltyMode=`
  popclip.openUrl(url, {app: 'com.google.Chrome'})
