How to define input field (Selector) under condition to exist text in other class in the same div

I'm having trouble defining the field for typing text into

this.requiredField = Selector('input').withAttribute('required');

in a condition where the validation label is

this.requiredLabel = Selector('.form-control-warning').withText('Required field cannot be left blank');

There are in class=”col-10” – see below

I am not interested in such a filed where there is no text Required field cannot be left blank in. form-control-warning

I need it because I must type text in each field with a label: 'Required field cannot be left blank" I created sth like this:

while (await epgBoard.requiredLabel.exists)
{

await t.typeText(epgBoard.emptyRequiredField, 'ff')
}

I have no idea how to define such selector

this.emptyRequiredField = find in .col-10 -> input withAtrribute required where . form-control-warning has text Required field cannot be left blank

Could sb help me with this matter?
