How to show multiple chips in an input field?

I have an input field where the user can select multiple items. Currently, I am using chips to capture user input.

Design:

Problem

1. How to show N no of chips e.g 10 number of chips in this example?
2. User should be able to see all the selected chips

Constraint

1. The known solution to this problem is keeping expanding the input field. I do have a constraint not to expand the line. The input box height shouldn't be increased at any cost.

The interaction I thought of is adding a click + drag interaction in the input field which is certainly not intuitive.

What is the best way to solve this problem?
