Cookieless Embed: Each new LookerEmbedSDK.createDashboardWithId creates a new session

[francispoole]

I currently have cookieless embed dashboards being shown on multiple pages in our NextJS site. Looking at network requests, it seems that each time I navigate to a different page with a new dashboard it makes a new call to /acquire-embed-session to refetch the tokens.

This means that each page change needs to wait for the session to the recreated which can mean additional loading times for the dashboard. This also occurs if I have multiple dashboards on the same page - each makes it's own call to /acquire-embed-session.

My assumption was that, given valid tokens already exist, it would not need to do this for each new dashboard? Is this an error in my implementation or are the tokens directly tied to each dashboard and new ones are needed for each?
