Ag grid, calendar pop up in cell

Once in the past I succeeded to configure ag-grid column, in a way that the user was clicking on cell and then calendar was poping up. The user could select date. Now after hours of searching I did not find something useful. I found in the forum just one way by changing index.html. This is not feasible when I deploy the app in cloud. I am kind of sure that there is easier way. Because I remember that I’ve done it.

Any suggestion?
