CRM: Copy values of user multiselect to text field

Hello all,

We face a challenge in our mobile app. In the Web app it is possible to select multiple users in a multiselect user field.

Though, this field is not supported in the mobile app.
We need the values of this field to be in the mobile app, not the field itself.

It would be OK if we could copy the values of the multiselect user field in a text field using a formula field or a function. As far as we are concerned, this is not possible.

Do you know how to copy the values of a multiselect user field to another field?

best regard,
Wesley
