I wanted to change the title to “Open whiteboard”

You change it from main.json file.

"toolbar": {
    ....
    .....
    "documentOpen": "Open shared document",
}

My Changes are not reflected

Thank you

You need to build again…
I hope you are cloned from github repo of jitsi meet.

i had follow this link to install jitsi meet, (not clone the project )

In order to modify Jitsi Meet UI, you need to clone the repo.
