Not possible to set shared link's expiration date

[kkovaletp]

Describe the bug
I have some media shared with shared link functionality. When I press the ... menu of the link, I see the expiration date checkbox and the text input field, but after enabling the checkbox and typing the date (in a few most common formats) into the field, I couldn't apply and save it, as there is no any button or arrow (like for the password) to initiate form submit. Once I click anywhere else and reopen the ... menu, the expiration date is empty and disabled.

To Reproduce
Steps to reproduce the behavior:

1. Go to any media details with the shared link created or create a new link for any media or album
2. Click on '...' button next to the link value to open the menu
3. Enable the expiration date checkbox and type some value
4. Try to save your changes
   --> No controls to do that
5. Click anywhere else and open that menu again
   --> The checkbox and the field are empty

Expected behavior
A minimal working solution would be to have a similar arrow, like in the password field. Once pressed, the value is converted into the DateTime format and sent to the server, stored in the DB.
A preferred solution would be to have a calendar pop-up opened once the user clicked on the field and once the date is selected there, it is automatically sent to the server - in this way, it is much more clear to the user, and no need to guess on the format.

Screenshots
It is pretty obvious and doesn't require screenshots. Also, I don't see the attachments functionality here, and I don't have an image-sharing service available on the internet.
