Tabs in detail view with dashboard view. It works, but it doesn't show Edit button in mobile&tablet

Hello, I followed  @Marc_Dillon  (thanks so much!) instructions in the post https://www.googlecloudcommunity.com/gc/Tips-Tricks/Tabs-in-Detail-Views/m-p/281110

It works but the Edit button does not appear in the mobile & tablet views , however it does appear in desktop view.

Does anyone know the reason?

Thanks

In mobile view ---> Edit button does'nt appears

In tablet view ---> Edit button does'nt appears, but I can maximice the tab and then edit

In desktop view ---> Edit button appears in any tab and I can maximice the tab too

You need to go to seetings > Views > view type option > show primary action in dashboard views
