Galaxy Wear(able) app or Galaxy Fit 2 app for iPhone

I have an iPhone XS, latest IOS and enough ram to be able to use the Samsung Galaxy Fit2 watch and connect it to my iPhone.

I installed the Galaxy Fit app and try to scan for nearby devices but my watch is not found.. I have connected it with Bluetooth successfully but the app can’t find my fit2 watch..

I saw several videos and articles that I have to install the Galaxy Wear(able) app but can’t find it in the App Store.

I also saw another apple discussion where someone had the same issue but apple support provided an article on how to connect accessories to your iphone using Bluetooth.

does anyone have the same issue? Is this normal? How should I connect the fit2 watch with my Iphone and start using it?

i would appreciate your help
