If you only have append access then all you will be able to do is issue a `PATCH` request without reading the file in advance; doing so is not currently supported by `solid-client-js`. Instead you can issue the `PATCH` request directly by calling the `fetch` function given to you by your session created form the `solid-client-authn` libraries.

You can see a sample patch request [here](https://forum.solidproject.org/t/error-when-trying-to-patch-a-resource-on-solid/2894)

[Comunica](https://github.com/comunica/comunica-feature-solid) and [rdflib.js](https://forum.solidproject.org/t/sparql-update-general-questions/4935/2) also supports PATCH requests if you want to use those libraries.
