I'm trying to connect by existing Clerk app (call it app A) to Vercel through Clerk integration on Marketplace. But at the step to choose Clerk apps, Vercel did not recognize my app. It just showed "No Clerk applications were found".

I then created a new app in Clerk to test this (call it app B), and it worked well with B.

What I have done:

• Create more apps in Clerk to test. It's all the same as B

• Check my personal workspace, there used to be a app with the same name as A, but I deleted it. Now personal workspace is totally empty. Can the old app be a problem?

• Checked that all env vars for Clerk is cleared

I'm running out of ideas. Anyone knows how I can make Vercel see my Clerk app? Or at least how to diagnose this problem?

For example, how do I check which workspace(s) in Clerk the Vercel integration was searching in?
