Use route in prestashop 1.7

[S.A]

Hello 

I write this route. How I can use this route in link 

This is my route function:

public function hookModuleRoutes()

{

return [

'module-mymodule-route' => [

'controller' => 'controllerfile',

'rule' => 'mymodule/validate',

'params' => [

'fc' => 'module',

'module' => 'mymodule'

]

]

];

}

I want call this route in other function, and become link like this:

http://localhost:8807/prestashop_1.7.7.2/?rest_route=/mymodule/validate

Thank you
