Cannot add Google calendar iframe

Hello everyone,

I would like to be able to add my Google calendar into Logseq. I use the iframe code share by Google under Calendar Settings > Integrate calendar > Embed Code.

The calendar is private and so ask to login. I cannot login.

I see the following error in the console:

Refused to frame '' because an ancestor violates the following Content Security Policy directive: "frame-ancestors".

As it is working in Obsidian, I inspect how do they include the iframe there. I added the sandbox attributes (sandbox="allow-forms allow-presentation allow-same-origin allow-scripts allow-modals") as they have it in Obsidian, but still does not work.

Is the problem on my hand or on Logseq?

Maybe it relates to the fact Obsidian use app:// vs logseq using file:// protocol. But to be honest, I do not know.
