If you have a friend, then ask for him/her to lend some tokens for gas fee. This is another way to if there's not enough gas fee. The other way also is to buy tokens like BNB using your Fiat Money. It will not move forward unless you have enough funds for the gas fee.
I think the OP already knows the best way to send the assets he owns, because so far the OP has had no response, even though when using the BNB network the transaction fees required should be very cheap and easy to reach.
That's right, transaction fees for the bnb network are very cheap, unlike eth for example which requires expensive fees when we want to make a transaction.
However, if we really don't have the means to pay transaction fees, then we can ask our friends for help. I also often do it, and several friends I know also do it, we can help each other. Moreover, if we have been in this space for a long time, we definitely understand what we have to do when we want to make a transaction.
