The Compute Dependencies utility menu item has been removed from version 23.2 (and possibly earlier) but is still available by modifying the URL.
For example, say this is your APEX instance URL (once you have navigated to your desired application).
https://hostname:port/ords/r/apex/app-builder/home?session=13766599855150
Change the URL after app-builder to the following, ensuring to add your current session_id (session) and app_id (fb_flow_id)
/database-object-dependencies?fb_flow_id=1234&session=13766599855150
Your URL should look something like this
https://hostname:port/ords/r/apex/app-builder/database-object-dependencies?fb_flow_id=1234&session=13766599855150
You will then be able to click the button to compute your dependencies.
