Not found (404) Removal Noindex URLs

Hi guys it's been week that I removed some content from my website and GSC sent me notification about Not found (404).
I submitted those URLs on Removals tool to tell google that I don't have those URLs and I don't wanna it on website.
but google keep send me this message "Page indexing issues detected"



What should I do? Wait until google got new update about site?
Or there is a way to get done immediately?

Ignore this notification and wait GSC is too slow they will update once crawler revisit your website it will take few weeks.

Or

Just 302 redirect all 404 pages to homepage
