Description of the flow steps: 1. split the list of identifiers using allows separators, 2. build a MIQL query with these identifier in preparation of running a PSICQUIC request, 3. Retrieve molecular interaction from IntAct's PSICQUIC service using the generated MIQL statement, 4. filter the list of returned MITAB using the list of identifiers and only keep those lines where both participating molecules are members of the input list, 5. return the count and list of filtered MITAB lines.
