Delete an attachment in a CDS gallery

I posted this but think I posted in the wrong section (Dataverse).

Anyone know what OnSelect code I use to delete an attachment from a Gallery in a Canvas App? The backend tables are in CDS.

I am trying with this code but nothing is happening: Remove(BrowseGallery1.Selected.'{Attachments}',ThisItem)

Here is another screenshot of how the attachments are setup in the gallery. You can see they are visible in a gallery, so I would hope its simple to write some code that when you select the Trash Icon in the gallery , it will delete the attachment. Any ideas anyone?

Put this code on OnSelect property of the trash icon which you have taken in your PhotoGallery
Remove(Tablename,ThisItem)

sorry for the mistake ThisItem should be in Camel case
If it works then Please Accept it as Solution
Thanks

@goel_gagandeep
I fixed the caps to ThisItem. but getting a new error:

Here how I have the gallery set:
Items = BrowseGallery1.Selected.'{Attachments}'
I have an image in the gallery set to this:
Image = ThisItem.Value
This displays all the attachments.
Then I have an Icon in the gallery with your suggestion:
OnSelect = Remove('Customer Site Surveys',ThisItem)
But it is saying "Incompatible type. The collection can't contain values of this type."

You have to Change your Items property of the gallery use table name as an items of the gallery instead of BrowseGallery1.Selected.'{Attachments}'

@goel_gagandeep And I suspect this is my challenge. Since I am trying to show attachments from a CDS table, I needed to use the below code on the main gallery.
So I have a main gallery (BrowseGallery1)
This provides a gallery of all the 'Customer Site Survey' entries based on some filter/search in this gallery. When I select an item. It brings me to a page with the attachments on display in another gallery (Gallery2).
This is why I have the Items = BrowseGallery1.Selected.'{Attachments}'
How would I change this to use the Table name, if the content is coming from the previous BrowseGallery1.Selected data?

@SBax Would you have any thoughts on how to do this? Would you need any more info to help diagnose my question on how to delete attachments?
