Nextcloud, delete requests not working

My YunoHost server

Hardware: VM
YunoHost version: 11.2.8.2
I have access to my server : Through SSH | through the webadmin | direct access via keyboard / screen
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no

Description of my issue

I seem to be unable to do the following in my Nextcloud installation:

  1. Delete files permanently from the trash bin
  2. Delete custom icons uploaded to the External Sites app

Searching around led me to this issue: Impossible to delete custom icon for external website due to nginx rejecting DELETE requests · Issue #580 · YunoHost-Apps/nextcloud_ynh · GitHub

It seems Yunohost Nextcloud’s nginx configuration rejects DELETE requests?

I really need to be able to delete files normally. Can someone please help me edit the configuration so that it works? I have no clue how to do it myself.

  # that file is correctly served; if it doesn't, then the request is passed to
  # the front-end controller. This consistent behaviour means that we don't need
  # to specify custom rules for certain paths (e.g. images and other assets,

  # `try_files $uri $uri/ /nextcloud/index.php$request_uri`
