Share/Interact another website without leaving Jitsi-meet

Hi There,

jitsi is great and I am a newbie…
I started to try adding features to jitsi meet.

my question: I would like to add a button to the advanced settings and
open an url inside jitsi-meet like sharing the youtube video…
I think it would be possible to create a container and
load the website inside this container… and add a mediastream…
So I can interact with the website without leaving the video chat.
Just me the moderator can use the website,
but the particpants can see what I am doing.

Can this be done inside Jitsi-Meet?
Do you have a rough path for me,
how I can realize this feature?

thank you in advanced and best wishes
