Custom form, resource creation and assignment through a many-to-many relationship of other resources

Please guide me, I understand that in Filament it should be possible to create a custom form where such a scenario could be implemented. My scenario (see screenshot), you need to select a supplier and a warehouse that belongs to the specific model (resource). After that, through select with search, select products that will relate to this resource (many 2 many). And then this state must be transferred to a custom saving method or through API call, in order to create a resource as part of a transaction and then attach the selected products to it.
