see here: https://dev.textgridlab.org/doc/services/submodules/tg-crud/tgcrud-webapp/docs/index.html#delete
compare here: https://restfulapi.net/http-methods/#get "Use GET requests to retrieve resource representation/information only – and not to modify it in any way. As GET requests do not change the state of the resource, these are said to be safe methods."
