Sharing link in slack shows Jitsi-meet with logo

Hello…I thought I fully rebranded jitsimeet with our company branding. We use docker-jitsi-meet.

However when I shared the link of our hosted jitsi-meet in slack to a colleague… slack showed jitsi-meet logo with full bold Jitsi-meet in the end. Where did I miss this out in the source. can someone help

awesome thanks a lot @damencho
