Magento2 OR query on collection

Question

We have been trying to make a query when a user apply some filters on front end. We are trying to make OR query in products collection: tried the following but none of them work

$collection->addAttributeToFilter(['web_mobile_filter','offer_group_name_value'],
            [
                ['in' => '1122'],
                ['in' => '72']
            ]);

and

  $collection->addAttributeToFilter(
        [
            [
                'attribute' => 'web_mobile_filter',
                'in' => '1122'
            ],
            [
                'attribute' => 'offer_group_name_value',
                'in' => '72,73'
            ],
        ]
    );

Can someone help me, find me what i am doing wrong here please?
