How to use wildcard characters in ts typeorm?

I’m coding a query in my NestTs project, so I would like to retrieve information matched with LIKE clause values. the problem with my query is the table has three types of records ‘_INFORMED’, ‘_UNINFORMED’ and ‘WITHOUT’. If I use the sentence .where(“user.firstName like :name”, { name:%_INFORMED% }) It matches with _INFORMED and _UNINFORMED records, then I tried to use the wildcard character as to standard SQL ‘%_INFORMED%’ but it looks wrong. Do you have any idea? Thanks!
