**As** a User/Admin/everybody
**I want to** use the link to local URLs, application URLs, other other non-http(s) URLs that the browser supports
**so that** we can use it with existing DMS, and other local applications

**Examples:**

* Application URL schemes:

* vis://FE0E3D1D-9DC5-4931-BF6C-9E01216047A4/3/8326584

* dict://term lookup

* vscode://file/path/to/file

* • figma://

* element://vector/webapp/#/room/!ID

* tel://number

* sms://number

* facetime://number

* Provide working links to `file://` local links, which all modern browsers block. The configuration will allow to whitelist them, but will be able to provide a working link
