to answer your question, you need to go to the person page (your wife’s) and edit it, then under events choose the appropriate event role. It’s the same as in Gramps desktop actually.
However, I suspect this is a case of XY problem. In Gramps (desktop or web), you add a married couple as father and mother to a family (doesn’t matter if they have children), then add the marriage event as an event to the family, not the individual people. The event then only has one participant - the family - with role “Family”. The reason for following this “canonical” approach is that most reports expect it to be that way.
The approach I described still works e.g. for adding people with other roles, like celebrants or witnesses.

But it will be my wife’s separate event, not ours. It’s very odd that event has “Participants” list even with different roles but in reality there can be only one participant:) Kinda misleading)

Looks like this is the only proper way right now, thanks!
This is a misunderstanding. There are very important uses of the participant roles also for marriages. For instance, I almost always add the “Celebrant” and “Witness” roles.
Be careful to set the Role as you share the Event.
There is enough context when creating a new Event for Gramps to guess that the Role should be “Primary” or “Family”. But when adding an existing Event to the next Person(s), that context is lacking. So the shared role defaults to “unknown”
