‘Link to’ gallery option disappeared in the Gutenberg editor

Do you mean the option here? https://www.ads-software.com/documentation/files/2019/05/Screenshot_27.png

I think it can now be found at the link. If you have the block active, look above the images in the options bar. There is a link symbol there. If you click on it, you can select a link destination. You can find more options by clicking on the down arrow.

Is that what you are looking for?

Thank you! You solved my problem. I now understand that the option is now located elsewhere. I found her. Thank you very much!

Blessings!
