* A _New wiki page_ dialog will appear:

* The user will be invited to enter a title for the Wiki.

* In the future, they will also be able to select the Space to which this Wiki will belong.

* The newly-created wiki page will appear in the Wiki tab since it is also automatically linked with the work package.

* If the link was created in-line, a corresponding link will appear. Clicking on this link will take the user to the newly-created page on XWiki.

End of the insertion Begin of the deletion Implementation

* Prerequisites:

* (assumed to be present) OpenProject's rich text editor has a generic slash-command UX pattern implemented, generically allowing "providers" to register commands (Currently not yet available. Implementation outside the scope of this here. Will be done by OpenProject independently)

* (assumed to be present) XWiki API for listing spaces

* (assumed to be present) XWiki API for listing pages, optionally filtering by space

* (Implementation needed in XWiki) XWiki API for pages that allow for creating a link to a OpenProject work package

* (Implementation needed in XWiki and OpenProject) Bi-directional OAuth setup on administrator level. Defined in ##55601.

* Slash command editor macro "Create new wiki page"

* Effort:

* UI to guide the user to grant OpenProject access to XWiki via OAuth unless a valid access token is already present.

* Implement slash-command "provider" for **creating** wiki pages

* Modal window with a form for creating a wiki page

* Inputs

* Select target space

* Select target page

* Text field for page title

* On form submit

* create page by sending a POST request to XWiki to create the page

* send POST request to XWiki to create the link between work package and freshly created wiki page

* Show optional link "Edit page in XWiki"

* On modal close

* send POST request to XWiki to create the link

* update the current work package "Wiki" tab to show new link

* Insert OpenProject rich text editor macro for showing a link to the wiki page.
