How can I refresh data on LWC which is received by Apex method imperatively?

Question

I have written wire and if data is received successfully I am calling function in which apex method is called imperatively, so how can I refresh results of that apex call for example on button click without refreshing the whole page? I tried to use refreshApex but that can only be used with wired result but it is not refreshing data which is returned after I call the function inside that wire, so here is the code:

import {
    LightningElement,
    track,
    wire
} from 'lwc';
export default class Sf_addProducts extends LightningElement {
    records = [];
    @wire(getFieldsLabelsMap) wiredQlis(result) {
        if (result.data) {
            this.getQliRecords(result.data);
        } else if (result.error) {
            console.log(result.error);
        }
    }
}

getRecords(fldsMap) {
    getQlis({
        quoteId: this.quoteId,
        fieldsToQUery: fieldNames
    }).then(res = {
        if (res.length > 0) {
            this.records = res;
        }
    })
}

handleButtonClick() { //refresh getRecords without refreshin the whole page

}
