How to get F-Droid to find updates of itself – how to remove "ignored updates"?

I am using F-Droid and have found that newer versions of the F-Droid app are available that are not displayed when F-Droid checks for updates.

I've noticed that while viewing the F-Droid> Installed Applications options, F-Droid is listed there, but with the words "ignored updates" (maybe the wording is different, I'm using a translation).

There is no "Update" button on the app page, only "Start".

Is there a way to indicate that F-Droid is also checking for updates?

F-Droid has already been preinstalled with my shift phone. Therefore, there is this setting.
