Hi Felipe,
let me clarify one thing are you not able to configure on web ui and you are not able to see the configure page icon.
If it is the case we can check using the below process to get configure page icon.
This may happen due to in your business role doesn't have the below personalization in functional profile. or it may have the All_disabled.
Or you can add your assignment block by the below process. :
you can add AB that exists in the component by following the below process.
Step1 : open T.code : BSPWD_CMP_WB and open your component.
Step 2 : open the overview set and click on the configuration tab.
Here you can move your view form available to displayed.
Save the configration.
Check it on Web UI.
Thanks,
Venkat
