How to list all the issues on which I am a participant, watcher, the assigned person.

I am a complete newbie whose work is now managed in JIRA tickets (which are "issues", I think.).  I tried to used the Search widget from the screen of the project's Kanban board. 

Since I have only worked on one project, I didn't specify the project. 

For the search I inputted: 

'"Request participants" = currentUser() Or watcher = currentuser() or assignee = currentuser()

based on another post here.

The response was:

Unable to parse the text '"Request participants" = currentUser() Or watcher = currentuser() or assignee = currentuser()' for field 'text'.

Any help will be appreciated!
